toLowerCase(), not tolowerCase()

shorter is:

<td style="cursor:pointer" onclick="
   var a = this;
   while(a.tagName.toLowerCase()!='tr') a=a.parentNode;
   a.parentNode.removeChild(a);
">

or 

<td style="cursor:pointer" onclick="
   var a = this;
   while( !/tr/i.test(a.tagName) ) a=a.parentNode;
   a.parentNode.removeChild(a);
">

but what is wrong with:

<td style="cursor:pointer" onclick="
   var a = this.parentNode;
   a.parentNode.removeChild(a);
">

Surely the parentNode of a <td> always is a <tr>?

from one of justaguy posts I understood that he wanted to remove the 
table containing the row of the clicked cell

the problem I saw in justaguy's code is that the table to remove isn't 
in the cell of a row of the parent table

By there I can't expect that the TD will be in a TR nor the TR in a 
TABLE (so backwards in code)

OOOooops !!!

Not at all sure with the html code of "justaguy" !!!

If I can make mistake I'm not alone :
that guy puts a table directly in a table
(not in the cell of a row of a table)

Then the code is in error.

A <td> has only and always one parent and that is an <tr>.

Ask just another guy.
