the top and left border of a table (border=1), and the bottom and right border of a cell, are drawn in a very faint grey, so they are almost invisible on a white background.

It will be very useful if you could attach a sample URL

When the body bgcolor is set to white the cell bottom border and right border are almost invisible. This is because of the condition in nsTableCellFrame.cpp that converts the borderColor to light gray. i.e., if (borderColor == 0xFFFFFFFF ) Line: 536 borderColor = 0xFFC0C0C0; Note: The borderColor gets the white color from the background color Changing the borderColor to black when the bgcolor is white solves the problem, i.e., if (borderColor == 0xFFFFFFFF ) Line: 536 borderColor = 0xFF000000; // instead of 0xFFC0C0C0 When no bgcolor is specified we don't see any problems with the cell border visibility. This could be because of the fact that the bgcolor is set to a default value ( mDefaultBackgroundColor = ::GetSysColor(COLOR_WINDOW); ) and that value somehow gets a darker shade to the border color. Waiting for your comments Steve.

I'm not sure where you're looking. nsTableCellFrame::MapHTMLBorderStyle() has this code: if (borderColor == 0xFFFFFFFF) borderColor = 0xFFC0C0C0; also, your comments don't address the table border itself (not just the cell borders.)
