No body will be able to answer this question without seeing the HTML output... but in a nutshell using javascript you loop through your table rows setting the style.display of a cell to none.
like
for (var r=0; row<tablerows.length;row++) {
rows[row].Cell[5].style.display='none';
}
This should hide the 5th index cell in each row of a table or hide the 6th column.

Or using server side code have a checkbox that does a postback removing the column.
