Quick and dirty sortable table for javascript. (I wrote this to embed in a single page html report.)

sort.js

function sortedTable(id) {
  var table = document.getElementById(id);
  table.lastColumn = -1;
  table.onclick = function(ev) {
    if (ev.target.nodeName == 'TH') {
      var row = ev.target.parentNode;
      for (var j=0;j<row.cells.length;j++) {
        if (row.cells[j] == ev.target) {
          var rows = [];
          for (var i=1;i<table.rows.length;i++) {
            rows.push(table.rows[i]);
          }
          if (j == table.lastColumn) {
            rows.reverse();
          } else {
            rows.sort(function(a,b) { return a.cells[j].textContent.localeCompare(b.cells[j].textContent) });
          }
          table.lastColumn = j;
          for (var i=0;i<rows.length;i++) {
            table.appendChild(rows[i]);
          }
          break;
        }
      }
    }
    return true;
  };
}
