Keep particular tag td always visible when scrolling

Question

This is my table in Html:

<div class="outer">
  <div class="inner">
    <table>
        <tr>
          <th >Header A</th>
          <td style="position:absolute; " >col 1 - A</td>
          <td >col 2 - A (COVER CONTENT)</td>
          <td >col 3 - A</td>
          <td >col 4 - A</td>
          <td >col 5 - A</td>
          <td >col 6 - A</td>
          <td >col 7 - A</td>
          <td >col 8 - A</td>
        </tr>
        <tr>
          <th>Header B</th>
          <td >col 1 - B</td>
          <td>col 2 - B</td>
          <td>col 3 - B</td>
          <td>col 4 - B</td>
          <td>col 5 - B</td>
          <td>col 6 - B</td>
          <td>col 7 - B</td>
          <td>col 8 - B</td>
        </tr>
        <tr>
          <th>Header C</th>
          <td>col 1 - C</td>
          <td>col 2 - C</td>
          <td>col 3 - C</td>
          <td>col 4 - C</td>
          <td>col 5 - C</td>
          <td>col 6 - C</td>
          <td>col 7 - C</td>
          <td>col 8 - C</td>
        </tr>

    </table>
  </div>
</div>

and CSS:

<style>

table {
  table-layout: fixed; 
  width: 100%;
  *margin-left: -100px;/*ie7*/
}
td, th {
  vertical-align: top;
  border-top: 1px solid #ccc;
  padding:10px;
  width:100px;
}
th {
  position:absolute;

  left:0; 
  width:100px;
}
.outer {position:relative}
.inner {
  overflow-x:scroll;
  overflow-y:visible;
  width:400px; 
  margin-left:100px;
}
</style>

I worked good when keeping tag <th> freezing, but I want to keep visible tag <td> with content "col 1 - A" by adding style="positon:absolute;" into <td> tag. it keep but the content of the other <td> cover it, that means "col 2 - A (COVER CONTENT)" and "col 1 - A" cover each other in the same cell.

p.s.: If I have tag <td rowspan="2"> how do I set position:absolute in this tag? I tried to add it into <td> but it just keep only one row.... Need help....
