Table cell borders and border-collapse - Page 1

Hi,

When I turn on border-collapse:collapse; on a table, some of the cell borders, like border-top:1px solid black; are not shown.

if I remove border-collapse:collapse;, the border-top shows fine.

In both cases, border-bottom works.

Is this a known issue?

it is because border-collapse disables border-left and border-top of each cell, except for the first column for border-left, and the first line for border-top
