<h1>TBODY/THEAD/TFOOT height redistribution.</h1>
<li>FF passes most of the tests.
<li>Legacy Chrome does not distribute TBODY height to rows.
<li>At the time this test was written, there was no spec. Currently, spec is in the process of being written.

<p>1) Empty row group's size is 0 with collapsed borders</p>
<table id="one" style="border-collapse: collapse;border-spacing: 10px 10px;border:10px solid green"
  data-expected-width="0" data-expected-height="0">
  <tbody>
    <tr> </tr>
  </tbody>
</table>
<p>2) Empty row group's size is 0 with separate borders.</p>
<table id="two" style="border-collapse: separate;border-spacing: 10px 10px;border:10px solid green"
  data-expected-width="20" data-expected-height="20">
  <tbody>
    <tr> </tr>
  </tbody>
</table>
<p>3) Row group height is redistributed to unconstrained rows in proportion to their size.</p>
<table id="three">
  <tbody style="height:100px" data-expected-height="100">
    <tr data-expected-height="25">
      <td><div style="height:10px" >0,0</div></td>
    </tr>
    <tr data-expected-height="75">
      <td><div style="height:30px" >0,0</div></td>
    </tr>
  </tbody>
</table>
<p>4) Constrained fixed rows do not grow if there are unconstrained rows</p>
<table id="four">
  <tbody style="height:100px">
    <tr style="height: 10px" data-expected-height="10">
      <td></td>
    </tr>
    <tr data-expected-height="90">
      <td>0,1</td>
    </tr>
  </tbody>
</table>
<p>5) Constrained percentage are resolved against row group height.</p>
<table id="five">
  <tbody style="height:100px">
    <tr style="height:25%" data-expected-height="25">
      <td>0,0</td>
    </tr>
    <tr style="height:50%" data-expected-height="50">
      <td>0,0</td>
    </tr>
    <tr data-expected-height="25">
      <td>0,2</td>
    </tr>
  </tbody>
</table>
<p>6) Row group height is treated as min-height.</p>
<table id="six">
  <tbody style="height:100px" data-expected-height="125">
    <tr style="height:125px">
      <td>0,0</td>
    </tr>
  </tbody>
</table>
<p>7) Constrained/unconstrained mix: row group height is distributed to unconstrained cells.</p>
<table id="seven">
  <tbody style="height:100px">
    <tr style="height:20px" data-expected-height="20"><td>0,0</td></tr>
    <tr style="height:30px" data-expected-height="30"><td>0,1</td></tr>
    <tr data-expected-height="25"><td>0,2</td></tr>
    <tr data-expected-height="25"><td>0,3</td></tr>
  </tbody>
</table>
<p>8) Unconstrained empty rows grow to fill table if all other rows are constrained. Not in FF.</p>
<table id="eight">
  <tbody style="height:100px">
    <tr style="height:20px" data-expected-height="20"><td>0,0</td></tr>
    <tr style="height:30px" data-expected-height="30"><td>0,1</td></tr>
    <tr data-expected-height="50"><td></td></tr>
  </tbody>
</table>
<br>
<table id="eightplus">
  <tbody style="height:100px">
    <tr data-expected-height="50"><td></td></tr>
    <tr style="height:20px" data-expected-height="20"><td>0,1</td></tr>
    <tr style="height:30px" data-expected-height="30"><td>0,2</td></tr>
  </tbody>
</table>
<p>9) Empty section height is not ignored</p>
<table id="nine" >
  <tbody style="height:75px"  data-expected-height="75">
  </tbody>
</table>
<p>10) Section with empty rows is not considered empty.</p>
<p>In FF, empty section height is 100, but table's height is 0?</p>
<table id="nine" >
  <tbody style="height:75px"  data-expected-height="75">
    <tr data-expected-height="25"></tr>
    <tr data-expected-height="25"></tr>
    <tr data-expected-height="25"></tr>
  </tbody>
</table>
<p>11) Mixed constrained and unconstrained empty rows: only unconstrained rows grow.</p>
  <table id="ten" style="width:50px">
  <tbody style="height:50px"  data-expected-height="50">
    <tr style="height:0" data-expected-height="0"><td></td></tr>
    <tr data-expected-height="25"><td></td></tr>
    <tr data-expected-height="25"><td></td></tr>
  </tbody>
</table>
