This is how I accomplished reading a table in javascript. Basically I drilled down into the rows and then I was able to drill down into the individual cells for each row. This should give you an idea

var oTable = document.getElementById('myTable');  
//gets table

var rowLength = oTable.rows.length;  
//gets rows of table

for (i = 0; i < rowLength; i++)\{  
//loops through rows

var oCells = oTable.rows.item(i).cells;  
//gets cells of current row  
var cellLength = oCells.length;  
for(var j = 0; j < cellLength; j++)\{  
//loops through each cell in current row  
  
  
\}  
\}  
UPDATED - TESTED SCRIPT

<table id="myTable">  
<tr>  
<td>A1</td>  
<td>A2</td>  
<td>A3</td>  
</tr>  
<tr>  
<td>B1</td>  
<td>B2</td>  
<td>B3</td>  
</tr>  
</table>  
<script>  
var oTable = document.getElementById('myTable');  
//gets table

var rowLength = oTable.rows.length;  
//gets rows of table

for (i = 0; i < rowLength; i++)\{  
//loops through rows

var oCells = oTable.rows.item(i).cells;  
//gets cells of current row  
var cellLength = oCells.length;  
for(var j = 0; j < cellLength; j++)\{  
//loops through each cell in current row  
  
var cellVal = oCells.item(j).innerHTML;  
alert(cellVal);  
\}  
\}  
</script>
