+<h1>Colspan&gt;1 width redistribution</h1>
+<p>TD with colspan&gt;1  redistributes its min/max/percent widths to the spanned cells.</p>
+<p>Creating explainable tests with percentage cells is complicated. Cell's percentage cannot be observed directly, but must be inferred from td+table widths. Rules that govern relationship between table grid width and percentage cell width are:</p>
+<ol>
+  <li id="rule1"><span  class="rule1">Rule#1</span>, Each percentage column sets the floor for  maximum table width. That table width is column.min_width / column.percent * 100.<br> Ex: 20px wide column, with 20% width, implies that the entire table must be at least 100px wide.</li>
+  <li id="rule2"><span class="rule2">Rule#2</span>, Sum of all percentages, combined with sum of widths of all non-percentages sets the floor maximum table widths. <br>Let P% be sum of all percentages, and Fpx sum of widths of all non-percentage columns. Maximum table width = Fpx * (1 + (100-P%)/P%).<br>
+  Ex: if percentage columns are 20%, and non-percentage columns are 100px, implies that that 80% is at least 100px, and that the entire table is at least 125px.
+  </li>
+</ol>
+<h2>Test design</h2>
+<p>All examples have border-spacing:8, td.padding:0.</p>
+<p>Tests are mostly tables with 2 rows. 1st row are the columns, 2nd row is the colspan&gt;1 column being distributed. Most test's colspan&gt;1 cell colspan encloses all cells except the last one. Each test is accompanied by test description. Test description contains:</p>
+<ol>
+  <li>First line describes the test geometry: cell:css/min/max. C1:20%/20px means width:20%, intrinsic min width 20px. If max is omitted, min == max.</li>
+  <li>Second line describes algorithm being tested in detail</li>
+  <li>Third line describes computation that generates the result.</li>

+Assignable width is 492. C0 gets 342, C1 get max:150
+Chrome Legacy does something very different to arrive at the same answer.
+Initial min/max is the same.
+Min gets distributed to C0 and C1 in proportion to max_width: C0:342/40 C1:150/150,
+Min also gets clamped to css width. This is the key difference betweeen NG
+and Legacy code. NG cannot clamp to css width, because it is not available.
+Max gets distributed to both in proportion to max_width: C0:342/103 C1:150/389
+Assignable table width is: 492 (sum of min), min gets used as final width.
+
+Analysis: colspan&gt;1 cell distribution over fixed/auto.
+Legacy incorrectly distributes minmax over both fixed and auto cells
+in proportion to max width,and clamps min to css width.
+
+This width becomes final width for auto tables without any further distribution.
+FF distributes min only over auto, and max over auto.
+Final distribution uses Guess 2 rules: start off with Auto(min), Fixed(max),
+distribute excess to Auto. Ends up with the same result as Legacy.</p>
