Implementing Rule G
§ 1194.22 Web-based intranet and internet information and applications.
(g) Row and column headers shall be identified for data tables.
Tables need to be defined so that row and column headers are clearly identified.
This means one cannot use tables presented using the <pre> tag,
which renders the table as a block of typed text, with no rows or columns tagged.
Tables must be marked up as tables with the <table> tag.
Column Headers
All column headers should be marked up using the <th> tag.
| Name | Address |
|---|---|
| Jane Doe | 123 Main Street |
| John Doe | 456 Sunset Avenue |
Code:
<tr><th>Name</th><th>Address</th></tr>
<tr><td>Jane Doe</td><td>123 Main Street</td></tr>
<tr><td>John Doe</td><td>456 Sunset Avenue</td></tr>
Row Headers
All row headers should be marked up using the <th> tag.
| Name | Jane Doe | John Doe |
|---|---|---|
| Address | 123 Main Street | 456 Sunset Avenue |
Code:
<tr><th>Name</th><td>Jane Doe</td><td>John Doe</td></tr>
<tr><th>Address</th><td>123 Main Street</td><td>456 Sunset Avenue</td></tr>
Usually, tables of the above structure will not be used, because if enough records are included, the number of columns in the table gets quite large and horizontal scrolling is necessary.
Complex Tables
See Implementing Rule H for information on marking up complex tables.
