如何在IE6中使用带有Prototype的Element添加<table>？

var newTable = document.createElement('table');
newTable.innerHTML = '<tr><td>Cell 1</td><td>Cell 2</td></tr>';

var element = $('elementId');
element.insert(newTable);

var newTable = document.createElement('table');
var newRow = newTable.insertRow(0);
var newCell1 = newRow.insertCell(0);
var newCell2 = newRow.insertCell(1);
newCell1.innerHTML = 'Cell 1';
newCell2.innerHTML = 'Cell 2';
