add extra column to table

lleming

Here is the problem. Table is used to show data recieved from server. Data comes in json format. It has a 5 columns. Now i have to add one more column where i will insert button(only for those rows which are have certain state in column 3). It will let me delete this row and corresponding record on server.

there are 2 ways to do it, as i do understand. First is to use some function to add column to table.
Second is to ammend data so each row will contain one more empty column.
