Tables are a powerful tool for presenting tabular data and for laying out text and graphics on an HTML page. A table consists of one or more rows; each row consists of one or more cells. Although columns aren’t usually explicitly specified in HTML code, Dreamweaver enables you to manipulate columns as well as rows and cells.
Dreamweaver displays the table width and the column width for each table column when the table is selected or when the insertion point is in the table. Next to the widths are arrows for the table header menu and the column header menus. Use the menus for quick access to common table-related commands. You can enable or disable the widths and menus.
If you do not see a width for the table or for a column, then that table or column does not have a specified width in the HTML code. If two numbers appear, then the visual width as it appears in Design view doesn’t match the width specified in the HTML code. This can happen when you resize a table by dragging its lower-right corner or when you add content to a cell that’s larger than its set width.
For example, if you set a column’s width to 200 pixels and then add content that stretches the width to 250 pixels, two numbers appear for that column: 200 (the width specified in the code) and (250) in parentheses (the visual width of the column as it’s rendered on your screen).
You can also lay out your pages using CSS positioning.
When formatting tables in Design view, you can set properties for the entire table or for selected rows, columns, or cells in the table. When a property, such as background color or alignment, is set to one value for the whole table and another value for individual cells, cell formatting takes precedence over row formatting, which in turn takes precedence over table formatting.
The order of precedence for table formatting is as follows:
For example, if you set the background color for a single cell to blue, then set the background color of the entire table to yellow, the blue cell does not change to yellow, since cell formatting takes precedence over table formatting.
When you set properties on a column, Dreamweaver changes the attributes of the td tag corresponding to each cell in the column.
You can merge any number of adjacent cells—as long as the entire selection is a line or a rectangle of cells—to produce a single cell that spans several columns or rows. You can split a cell into any number of rows or columns, regardless of whether it was previously merged. Dreamweaver automatically restructures the table (adding any necessary colspan or rowspan attributes) to create the specified arrangement.
In the following example, the cells in the middle of the first two rows have been merged into a single cell that spans two rows.
Use the Insert panel or the Insert menu to create a new table. Then, add text and images to table cells the same way that you add text and images outside of a table.
Specifies the width of the table in pixels, or as a percentage of the browser window’s width.
When you don’t explicitly assign values for border thickness or cell spacing and cell padding, most browsers display the table border thickness and cell padding set to 1 and cell spacing were set to 2. To ensure that browsers display the table with no border, padding or spacing, set Cell Padding and Cell Spacing to 0.
Makes the first column of the table a column for headings, so that you can enter a heading for each row of the table.
Makes the first row of the table a row for headings, so that you can enter a heading for each column of the table.
It’s a good idea to use headers in case any of your website visitors use screen readers. Screen readers read table headings and help screen-reader users keep track of table information.
You can import tabular data that has been created in another application (such as Microsoft Excel) and saved in a delimited text format (with items separated by tabs, commas, colons, or semicolons) into Dreamweaver and format it as a table.
You can also export table data from Dreamweaver into a text file, with the contents of adjacent cells separated by a delimiter. You can use commas, colons, semicolons, or spaces as delimiters. When you export a table, the entire table is exported; you cannot select portions of a table to export.
If you want only some of the data from a table—for example, the first six rows or the first six columns—then copy the cells containing that data, paste those cells outside of the table (to create a new table), and export the new table.
The delimiter used in the file you’re importing.
If you select Other, a text box appears to the right of the pop‑up menu. Enter the delimiter used in your file.
Specify the delimiter that was used when the data file was saved. If you don’t do this, the file will not be imported properly, and your data will not be correctly formatted in a table.
The width of the table.
Select Fit to Data to make each column wide enough to fit the longest text string in the column.
Select Set to specify a fixed table width in pixels or as a percentage of the browser window’s width.
If you don’t explicitly assign values for borders, cell spacing, and cell padding, most browsers display the table with borders and cell padding set to 1, and cell spacing set to 2. To ensure that browsers display the table with no padding or spacing, set Cell Padding and Cell Spacing to 0. To view cell and table boundaries when the border is set to 0, select View > Visual Aids > Table Borders.
You can select an entire table, row, or column at once. You can also select one or more individual cells.
When you move your pointer over a table, row, column, or cell, Dreamweaver highlights all the cells in that selection so that you know which cells will be selected. This is useful when you have tables without borders, cells that span multiple columns or rows, or nested tables. You can change the highlight color in preferences.
If you position the pointer over a table’s border, then hold the Control key (Windows) or Command key (Macintosh), the entire structure of the table—that is, all cells in the table—is highlighted. This is useful when you have nested tables and want to see the structure of one of the tables.
- Click the upper-left corner of the table to select the table.
- Click in a table cell, then select the tag in the tag selector at the lower-left corner of the Document window.
- Click in a table cell, click the table header menu, then select Select Table. Selection handles appear on the selected table’s lower and right edges.
- Click in a table cell, and select Edit > Table > Select Table.
Drag from a cell to another cell.
Click in one cell, Control‑click (Windows) or Command-click (Macintosh) in the same cell to select it, then Shift-click another cell.
If each cell, row, or column you Control‑click or Command-click isn’t already selected, it’s added to the selection. If it is already selected, it’s removed from the selection.
Select Highlighting from the category list on the left, make either of the following changes, and click OK.
To change the highlighting color for table elements, click the Mouse-Over color box, then select a highlight color using the color picker (or enter the hexadecimal value for the highlight color in the text box).
To enable or disable highlighting for table elements, select or deselect the Show option for Mouse-Over.
These options affect all objects that Dreamweaver highlights when you move the pointer over them.
You usually don’t need to set the height of a table.
Determines where the table appears, relative to other elements in the same paragraph, such as text or images.
Left aligns the table to the left of other elements (so that text in the same paragraph wraps around the table to the right); Right aligns the table to the right of other elements (with text wrapping around it to the left); and Center centers the table (with text appearing above and/or below the table). Default indicates that the browser should use its default alignment.
When alignment is set to Default, other content is not displayed next to the table. To display a table next to other content, use Left or Right alignment.
If you don’t explicitly assign values for the border, cell spacing, and cell padding, most browsers display the table with the border and cell padding set to 1 and cell spacing set to 2. To ensure that browsers display the table with no padding or spacing, set Border to 0, Cell Padding and Cell Spacing to 0. To view cell and table boundaries when the border is set to 0, select View > Visual Aids > Table Borders.
You might need to expand the Table Property inspector to see the following options. To expand the Table Property inspector, click the expander arrow in the lower-right corner.
Clear Column Widths and Clear Row Heights
and Clear Row Heights delete all explicitly specified row height or column width values from the table.
Convert Table Widths To Pixels
and Convert Table Heights To Pixels set the width or height of each column in the table to its current width in pixels (also sets the width of the whole table to its current width in pixels).
Convert Table Widths To Percent
and Convert Table Heights To Percent set the width or height of each column in the table to its current width expressed as a percentage of the Document window’s width (also sets the width of the whole table to its current width as a percentage of the Document window’s width).
Specifies the horizontal alignment of the contents of a cell, row, or column. You can align the contents to the left, right, or center of the cells, or you can indicate that the browser should use its default alignment (usually left for regular cells and center for header cells).
Specifies the vertical alignment of the contents of a cell, row, or column. You can align the contents to the top, middle, bottom, or baseline of the cells, or indicate that the browser should use its default alignment (usually middle).
W and H
The width and height of selected cells in pixels, or as a percentage of the entire table’s width or height. To specify a percentage, follow the value with a percent symbol (%). To let the browser determine the proper width or height based on the contents of the cell and the widths and heights of the other columns and rows, leave the field blank (the default).
By default, a browser chooses a row height and column width to accommodate and the widest image or the longest line in a column. This is why a column sometimes becomes much wider than the other columns in the table when you add content to it.
You can specify a height as a percentage of the total table height, but the row may not display at the specified percentage height in browsers.
Combines selected cells, rows, or columns into one cell. You can merge cells only if they form a rectangular or linear block.
Divides a cell, creating two or more cells. You can split only one cell at a time; this button is disabled if more than one cell is selected.
Prevents line wrapping, keeping all the text in a given cell on a single line. If No Wrap is enabled, cells widen to accommodate all data as you type it or paste it into a cell. (Normally, cells expand horizontally to accommodate the longest word or widest image in the cell, then expand vertically as necessary to accommodate other contents.)
Formats the selected cells as table header cells. The contents of table header cells are bold and centered by default.
You can specify widths and heights as either pixels or percentages, and you can convert from pixels to percentages and back.
When you set properties on a column, Dreamweaver changes the attributes of the td tag corresponding to each cell in the column. When you set certain properties for a row, however, Dreamweaver changes the attributes of the tr tag rather than changing the attributes of each td tag in the row. When you’re applying the same format to all the cells in a row, applying the format to the tr tag produces cleaner, more concise HTML code.
You can change the appearance of tables by setting properties for the table and its cells or by applying a preset design to the table. Before you set table and cell properties, be aware that the order of precedence for formatting is cells, rows, and tables.
To format the text inside a table cell, use the same procedures you would use to format text outside of a table.
When you set properties on a column, Dreamweaver changes the attributes of the td tag corresponding to each cell in the column. When you set certain properties for a row, however, Dreamweaver changes the attributes of the tr tag rather than changing the attributes of each td tag in the row, When you’re applying the same format to all the cells in a row, applying the format to the tr tag produces cleaner, more concise HTML code.
To quickly locate the tags in the code, click in the table, then select the <table> tag in the tag selector at the bottom of the Document window.
- To edit the table caption,
highlight the caption and type a new caption.
To edit the caption alignment, place the insertion point in the table caption, right-click (Windows) or Control‑click (Macintosh), then select Edit Tag Code.
To edit the table summary, select the table, right-click (Windows) or Control-click (Macintosh), then select Edit Tag Code.
You can resize an entire table or individual rows and columns. When you resize an entire table, all of the cells in the table change size proportionately. If a table’s cells have explicit widths or heights specified, resizing the table changes the visual size of the cells in the Document window but does not change the specified widths and heights of the cells.
You can resize a table by dragging one of its selection handles. Dreamweaver displays the table width, along with a table header menu, at the top or bottom of the table when the table is selected or the insertion point is in the table.
Sometimes the column widths set in the HTML code do not match their apparent widths on the screen. When this happens, you can make the widths consistent. Table and column widths and header menus appear in Dreamweaver to help you lay out your tables; you can enable or disable the widths and menus as necessary.
You can change the width of a column or the height of a row in the Property inspector or by dragging the borders of the column or row. If you have trouble resizing, you can clear the column widths or row heights and start over.
You can also change cell widths and heights directly in the HTML code using Code view.
Dreamweaver displays column widths, along with column header menus, at the tops or bottoms of columns when the table is selected or the insertion point is in the table; you can enable or disable the column header menus as necessary.
Select the table. If you are in Live view, Element Display is shown when you select the table. Click the sandwich icon to enter the table formatting mode.
To resize the table horizontally, drag the selection handle on the right.
To resize the table vertically, drag the selection handle on the bottom.
To resize the table in both dimensions, drag the selection handle at the lower-right corner.
To exit the table formatting mode in Live view, press Esc or click outside the table. You can use Edit > Table menu options to modify the table further.
Note: The options in Edit > Table menu vary based on whether you have selected the entire table or a single cell. In Live view, Element Display shows 'table' when the entire table is selected and 'td' when a specific cell is selected. To switch from a cell formatting to table formatting mode, click the table border.
The width of the adjacent column also changes, so you actually resize two columns. Visual feedback shows you how the columns will adjust; the overall table width does not change.
In tables with percentage-based widths (not pixels), if you drag the right border of the rightmost column, the entire table’s width changes, and all of the columns grow wider or narrow proportionately.
Pressing Tab in the last cell of a table automatically adds another row to the table.
Select Edit > Table > Insert Row or Edit > Table > Insert Column.
A row appears above the insertion point or a column appears to the left of the insertion point.
Click the column header menu, and then select Insert Column Left or Insert Column Right.
Click in a cell within the row or column you want to delete, then select Edit > Table > Delete Row, or Edit > Table > Delete Column.
Select a complete row or column, then press Delete.
- In the Property inspector (Windows > Properties), do one of the following:
- To add or delete rows, increase or decrease the Rows value.
- To add or delete columns, increase or decrease the Cols value.
Dreamweaver does not warn you if you are deleting rows and columns that contain data.
Select Edit > Table > Increase Row Span, or Edit > Table > Increase Column Span.
Select Edit > Table > Decrease Row Span, or Edit > Table > Decrease Column Span.
You can copy, paste, or delete a single table cell or multiple cells at once, preserving the cells’ formatting.
You can paste cells at the insertion point or in place of a selection in an existing table. To paste multiple table cells, the contents of the Clipboard must be compatible with the structure of the table or the selection in the table in which the cells will be pasted.
To replace existing cells with the cells you are pasting, select a set of existing cells with the same layout as the cells on the clipboard. (For example, if you’ve copied or cut a 3 x 2 block of cells, you can select another 3 x 2 block of cells to replace by pasting.)
To paste a full row of cells above a particular cell, click in that cell.
To paste a full column of cells to the left of a particular cell, click in that cell.
If you have less than a full row or column of cells in the clipboard, and you click in a cell and paste the cells from the clipboard, the cell you clicked in and its neighbors may (depending on its location in the table) be replaced with the cells you are pasting.
A nested table is a table inside a cell of another table. You can format a nested table as you would any other table; however, its width is limited by the width of the cell in which it appears.
You can sort the rows of a table based on the contents of a single column. You can also perform a more complicated table sort based on the contents of two columns.
You cannot sort tables that contain colspan or rowspan attributes—that is, tables that contain merged cells.
Determines whether to sort the column alphabetically or numerically, and whether to sort it in ascending order (A to Z, lower numbers to higher numbers) or descending order.
When the contents of a column are numbers, select Numerically. An alphabetic sort applied to a list of one- and two-digit numbers results in the numbers being sorted as if they were words (resulting in ordering such as 1, 10, 2, 20, 3, 30) rather than being sorted as numbers (resulting in ordering such as 1, 2, 3, 10, 20, 30).
Determines the sorting order for a secondary sort on a different column. Specify the secondary-sort column in the Then By pop‑up menu, and the secondary sort order in the Order pop‑up menus.
Sort Includes The First Row
Specifies that the first row of the table should be included in the sort. If the first row is a heading that should not be moved, do not select this option.
Sort Header Rows
Specifies to sort all the rows in the table’s thead section (if any) using the same criteria as the body rows. (Note that thead rows remain in the thead section and still appear at the top of the table even after sorting.) For information about the thead tag, see the Reference panel (select Help > Reference).
Sort Footer Rows
Specifies to sort all the rows in the table’s tfoot section (if any) using the same criteria as the body rows. (Note that tfoot rows remain in the tfoot section and still appear at the bottom of the table even after sorting.) For information about the tfoot tag, see the Reference panel (select Help > Reference).
Keep All Row Colors The Same After The Sort Has Been Completed
Specifies that table row attributes (such as color) should remain associated with the same content after the sort. If your table rows are formatted with two alternating colors, do not select this option to ensure that the sorted table still has alternating-colored rows. If the row attributes are specific to the content of each row, then select this option to ensure that those attributes remain associated with the correct rows in the sorted table.
