DataTables

Hi

I have a 2 col table, the first has limited data length, the second col contains longer texts (2-3 lines without CR/LF). I'd like to either set nowrap on the first col, or, preferably, allow it enough space with sWidth set to, say 30%. This works fine in FF7.0.1, but has no effect in IE8 or Chrome. DataTables Ver is 1.8.2 (same issue in 1.8,.1). Use of aoColumns or aoColumnDefs makes no difference.

     var options = {
//      "sScrollY": "450px",
      "sScrollY": "23px",
//      "sScrollX": "",
       "bInfo": true,         // show display summary
       "bAutowidth": false,
       "bPaginate": false,
       "bProcessing": true,   // Show 'processing' box during load
       "sAjaxSource": '/my_controller.js',
       "sDom": 'iflrtp<"clear">',  // i=info, f=filter  l=length  r=  t=table p=pagination
       "aoColumnDefs": [
         { "sWidth": "30%", "aTargets": [ 0 ] }
       ],
//      "aoColumns": [ { "sWidth": "650px" }, null ],

       // Get the table data
       j.getJSON( sSource, aoData, function (json) {
         // Fill the table with received data
         fnCallback(json);
       });
      },
    };

    oTable = j('#my_data_table').dataTable( options );

In IE8 & chrome the first col is very narrow - it looks like DT is assigning space according to longest text content ratio.
How can I override this?
