    Split is for a string. You are dealing with an array.

    return  data[0] + "<br /> + data[1];

    ooops, left off a quote above

    return  data[0] + "<br />" + data[1];

    Use Array.prototype.join to join an array.

    if your data is in the form of arrays of numbers as string as you show at the top,
    I built an array of numbers using random integers so it looks like;

    [ ["92", "94", "68", "6", "20", "8", "62", "17"],
["95", "77", "34", "93", "5", "74", "1", "44"],
["66", "82", "38", "60", "24", "77", "55", "35"],
["64", "18", "49", "98", "35", "58", "91", "76"],
["60", "23", "66", "72", "61", "37", "44", "18"] ]

    I created two tables, one that shows each value (8 x 10 table)

    I created a second table that is 4 x 10 table that combines numbers with a <br>. You can see it here http://live.datatables.net/qerogefi/1/edit

    $(document).ready( function () {
  
       // generate fake data string for testing then display it
      var data1 ="1";
      for(var i = 0; i < 16; ++i){
            data1 += "," + String(getRandomInt(1, 100));
       }
       $("#gennum").html(data1);
       // now turn the fake data into an array
       var data2 = data1.split(",");
       var colCount = Math.floor(data2.length/2 + data2.length%2);
       var cols = [];
       for(var j = 0; j < colCount; ++j){
           cols.push({data:null, title:"Set " + (j + 1)});
  
       }
       // now figure out how many columns I need
       
       // DataTable is expecting double dim array for rows and clolumns so 
       var data3 = [];
       data3.push(data2);
  
 
  var table1 = $('#example2').DataTable({data:data3,
      columnDefs:[{targets:"_all",
      render: function(data, type, row, meta){
          return row[meta.col * 2] + "<br/>" + (row[((meta.col * 2)+1)] ||"");
                                          
          }}],
       columns:cols
   });
                             
  
} );

function getRandomInt(min, max) {
  min = Math.ceil(min);
  max = Math.floor(max);
  return Math.floor(Math.random() * (max - min)) + min;
}
