Instead of adding column after column with information, making tables busy and sometimes impossible to fit in the screen, a good solution is a tooltip that will display more information when passing the mouse over the "?" icon at the begining of the table.
To add a tooltip simply use the $tooltip array variable, on each value of the array, add text :column_name
for example:
$tooltip = array(" Telephone:TEL, Email:EMAIL, Address:ADDRESS, Postal Code:ZIP ");
Another way:
$tooltip= array(); array_push($tooltip,"Telephone:TEL"); array_push($tooltip,"Email:EMAIL"); array_push($tooltip,"Address:ADDRESS"); array_push($tooltip,"Postal Code:ZIP");
The tooltip will show the information of each array value in a different line
Telephone: 514 123 4456
Email: [email protected]
Address: 1234 street name
Postal Code: A1B 1C2
