Fixit – Nested Tables

This test determines if your page make use of nested tables. Mobile devices often cannot display nested tables correctly. When a mobile device is capable of displaying nested tables, the computations required to render the tables can consume lot of CPU and add to the display time for the page.

Checking for nested tables

This test checks to see if any <table> element is contained within another <table> element. If any such table element is found, then the test reports a FAIL.

If you receive a FAIL for this test, you should consider other options such as splitting your nested table into separate tables.

Reference

This test is based on a W3C mobileOK best practice. See http://www.w3.org/TR/mobile-bp/#TABLES_NESTED for more details.
