IE7 problems with displaying text in TD

I can not figure out why the text inside the TD is not displayed in IE7. I am frustrated to the core cuz it works in FF! All I am trying to do is dynamically build a table onload... Any help will开发者_如何学Python be greatly appreciated. The complete script is at pastebin

User insertRow and insertCell to add Rows and Cells
Ex:

var row = table.insertRow();
row.id= rowid;

var headerCell = row.insertCell();
headerCell.colSpan = colspan;
headerCell.className = "rightAligned";
headerCell.innerHTML = "Header Text";

use the insertRow(-1) to add a row instead, and insertCell(-1) to add a column

IE needs a TBODY. Just add it as the first child of your table and then append your rows and cells to that.
