Testing in
TestOps/sec
jquery .append()
var rows = '';
for (var i = 0; i < nowNumber; i++) {
  var tr = '<tr>';
  for (var j = 0; j < columnNumber; j++) {
    tr += '<td>&nbsp;</td>';
  }
  tr += '</tr>';
  rows += tr;
}
$('#test').empty().append(rows);
ready
jQuery .html()
var rows = '';
for (var i = 0; i < nowNumber; i++) {
  var tr = '<tr>';
  for (var j = 0; j < columnNumber; j++) {
    tr += '<td>&nbsp;</td>';
  }
  tr += '</tr>';
  rows += tr;
}
$('#test').html(rows);
ready
javascript innerHTML
var rows = '';
for (var i = 0; i < nowNumber; i++) {
