HTML Checking for Large Sites
Rocket Validator integrates the W3C Validator HTML checker into an automated web crawler.
HTML issues tagged as range.
Table columns in range X…Y established by element “td” have no cells beginning in them.
A <table> contains an incoherent number of columns on one of its rows. Check the structure of the table to find the invalid row.
For example, in the following table, the first <tr> row defines that it’s 2 columns wide, but the second <tr> row tries to use 5 columns by means of a colspan attribute:
<table> <!-- This first row sets the table as 2 columns wide --> <tr> <td>First</td> <td>Second</td> </tr> <!-- This second row tries to use 5 columns --> <tr> <td colspan="5">Wrong</td> </tr> </table>
25,000 HTML checks per month. Fully automated.
