277251 - 1-pixel gap at bottom of table cell

Status: RESOLVED WORKSFORME

(Core :: Layout: Tables, defect)

Description

[Ilkka Priha]

When rendering a HTML page with a nested table structure to support columns with
diffent background colors, the background of the lowest pixels in the table cell
is not painted if:

1) The cell contains a list (HTML <UL> or <OL>) AND
2) The font size is smaller than 100 %

The same problem is in Mozilla browser.

Can't see the problem.
You have "background: #FFFFFF". Of course that cell will be white in background
color.

It's a bit more complicated. Originally, the left column is gray and the right
column is white. At the bottom of the right column, I want a block to share the
background of the left column. However, the very last line of pixels of this
gray block in the right column is left to original white, but only when there is
<ul> or <ol> somewhere in the upper (white) part of the left column and the font
size is set to smaller than 100%.

I noticed that this can almost be avoided by using some other font unit than %,
but then it reappears in some cases when the user applies text zoom. It renders
correctly in IE.

I can see it if I text-zoom to a rather large font (2005-01-02-06 Linux).
Looks like a rounding error...
