Im having some issues with datatables and internet explorer 8 ( Could also be other browsers, but works in IE9). I have spent some time trying to find out what the issue is and i have been unable, but i have figured out what javascript that seems to trigger it:

If i remove this code then it works in IE 8, can someone point out the error in my ways ?

The problem is most likely your last object in the aoColumns array:

    {"sType": "percent" },   
],

You've left the ma on the last entry. I made the same error and it worked happily with Firefox at least, but not IE 8.

Using this code fixed the problem for me, il leave the question open perhaps somone knows why it works with this change.

"aoColumns": [
    { "sType": "string", "sWidth": "auto" },                       // Player name
    {"sType": "numeric-minus", "sWidth": "auto" },                       // Damage done
    {"sType": "numeric-ma", "bVisible": false, "sWidth": "auto" },    // DPS real
    {"sType": "numeric-ma", "sWidth": "auto" },                       // DPS Avg
    {"sType": "numeric-minus", "sWidth": "auto" },                        // Damage taken
    {"sType": "numeric-minus", "sWidth": "auto" },                        // Healing done
    {"sType": "numeric-ma", "bVisible": false, "sWidth": "auto" },    // healing done HPS
    {"sType": "numeric-ma", "sWidth": "auto" },    // healing done HPS Avg
    {"sType": "numeric-ma", "sWidth": "auto" },                       // Overhealing
    {"sType": "numeric-ma", "sWidth": "auto" },                       // Healing taken
    {"sType": "numeric-ma", "bVisible": false, "sWidth": "auto" },    // Mana done
    {"sType": "numeric-ma", "bVisible": false, "sWidth": "auto" },    // Stamina done
    {"sType": "string", "bVisible": false, "sWidth": "auto" },            // Class
    {"sType": "percent", "sWidth": "auto" }                              // Activity
],

in my case using width="100%" in table caused the problem, removing width solved it.

working code

<table id="dt_table">
<thead>
<tr>
    <th>column1</th>
    <th>column2</th>
    <th>column3</th>
    <th>column4</th>
    <th>column5</th>
    <th>column6</th>
</tr>
</thead>
</table>
