its posible to add attr to a column and read it? to send data to db with ajax with toggles

I have many columns, the order and quantity its not always the same, and some hidden colums and left joins too. But some of this columns have toggles that send data to specific columns to db thru ajax.
The toggles can be at any position and can be more than one.
Im triyng to add attr to columns to read it and know the cell db and table were send the data.
