+ <p>Three columns are styled.</p>
+ <p>In the first column, there should be three vertical stripes along the padding edge of the first cell, continuing down through the column. (In cell E, the aqua stripe will be obscured by the thicker right border.) The stripes will cut across cell E as well, but will be further obscured by its thick border. In the border-collapsed table, the same will happen to the vertical stripes in cell A due to cell B's thick border. The stripes should continue in the last cell, turning a right angle to the left into three aqua stripes along the bottom border edge of the last cell. The last cell (M) should not have three vertical stripes along its right edge.</p>
+ <p>In the second column, three vertical strips should run along the right of the first three cells, aligning along cell F's right padding edge. (The stripes will be partially obscured by cell B's thick border.)</p>
+ <p>In the third column, there should be three vertical stripes should run across the top of the first cell and down the left of the column, aligning along cell K's left padding edge. In border-collapse mode, they will be partially obscured by cell B's thick border.</p>

+<h1>CSS2 Table Backgrounds Test Suite</h1>
+<h2>Notes</h2>
+<p>This test suite is not endorsed or approved by the W3C or anyone besides fantasai. It tests conformance to fantasai's <a href="../">table background clarification proposal</a>, not the official CSS2 specification. The intent is to demonstrate the proposal's effects under various styling conditions and to clarify any ambiguity in the proposal in preparation for a better-worded errata suggestion. It's not particularly well-designed, but it is comprehensive.</p>
+<p>This test suite (this page and all pages linked from the table of contents below) and its background images (listed below) are in the public domain by assertion of their author. No rights reserved.</p>
+<p>The images used as backgrounds are the following:
+ <ul>
+ <li><img alt="rainbowh.gif" src="rainbowh.gif">
+ <li><img alt="rainbowv.gif" src="rainbowv.gif">
+ <li><img alt="edge.gif" src="edge.gif">
+ </ul>
+<p>They are in GIF format, with transparency.</p>
+<p>Each color band in the rainbow backgrounds is 20 pixels wide. Each stripe within the color band is two pixels wide.</p>
+<p>The aqua and purple band is 10 pixels wide. Each stripe within the band is two pixels wide.</p>
+<p>Many image background rules in this test suite are backed up with a 'black' background color.</p>
+<p>This test suite assumes that <strong>the border edge for a table element in a table with collapsed borders is the <em>middle</em> of the border around the element, not the outer or inner edge.</strong> (This also needs to be addressed by CSS2.1.) It also assumes support for proper ordering of tables with <code class="sgmltag">&lt;tfoot&gt;</code>.</p>
