title: multiple dimension in dataTable dc.js
body: <p>I have 5 columns <code>pid, cid, date, types, probability</code> in datatable. I am able to filter by a single column (<code>pid</code>) but I want to filter by other column values also.</p>

  <pre><code>// Setup different dimensions for plots
  dim.tableMaxConfidence = cf.dimension(function (d) {
    return d.pid;

  <p>I have to make it for multiple dimension filtering. </p>

  <pre><code>.on('pretransition', function (table) {
       table.selectAll('td.dc-table-column._0')
            .on('click',function(d){
                  console.log(d);
                  table.filter(d.pid)
                  dc.redrawAll();
             })

                  console.log("select:",d);
                  table.filter(d.cid)

                  table.filter(d.date)
                  dc.redrawAll();
             })
        table.selectAll('td.dc-table-column._4')
           .style("background-color", function(d){ 
            return color(d.probability)});
    });

  <p>This works only for pid since there is only pid in dimension.</p>
  
  <p>So my question is it possible to filter by other column values also. If yes, then How?</p>
  
  <p>Any hint will be appreciable.</p>
