	----------------------------------------------------------------------------------
	Table sort function by Roman Koch rewritten/adapted 
	to be ECMA compliant for PGE.com by Jeff Held (j0hg).
	----------------------------------------------------------------------------------
	This code allows table data to be sorted. clicking once sorts ascending, clicking a second time sorts descending.
	This script is dynamic, your table can have any combination of columns and rows
	Use a table calling the function in the table head with a link:
	<table>
		<thead>
			<tr>
				<th><a href="#" onclick="TableSort('tableName',0,'a');">LanID</a></th>
			</tr>
		</thead>
		<tbody id="tableName">
			<tr>
				<td>j0hg</td>
			</tr>
			<tr>
				<td>dpw8</td>
			</tr>
		</tbody>
	</table>
	
	Note that the function call is the same as the id of the table body:
	TableSort('(id of table body)',column number (0 is first),'method of sort')
	method of sort is as follows:
	a - compare alphabetically
	ai - compare alphabetically ignoreing case
	d - sort by date (date must be a valid date)
	n - sort numerically
