Hidden Columns Still Showing

dellaboemia

I'm not clear on precisely how to hide a column. I've implemented two tables on the same page. For the first table, I simply assigned the field's type attribute a "hidden" property. I did this in the table.tablename.js file. It worked. However, it's not working for the 2nd table. Please advise.

Here's the code
'''
(function($){

$(document).ready(function() {
var editor = new $.fn.dataTable.Editor( {
