CSS GUIDE BORDER COLLAPSE
This document is a work in progress and is subject to change.
Contents
Summary
The border-collapse property is used to make the border collapse. This has a big influence on the look and style of the table cells.
The rendering of table borders is divided into two categories in CSS2 - "collapsed" and "separated". This property specifies which border rendering mode to use. In the collapsed border model, adjacent table cells share borders.
In the separated model, adjacent cells each have their own distinct borders (the distance between them given by the 'border-spacing' property.)
Inherited: Yes
Initial : seperate
Media : Visual
Syntax

Mozilla Recommended Values
Usage Examples
table border="1" style="border-collapse: collapse" bordercolor="#111111" width="500"
table border="1" style="border-collapse: separate" bordercolor="#111111" width="500"
Notes
In the "collapsed border" rendering model, the 'border-style' value of "inset" behaves like "groove", and "outset" behaves like "ridge." CSS2 specifies that the initial value for this property is "collapse", but CSS2.1 and Mozilla/Opera all state or behave such that the initial value is "separate."
