Column prefix
Hi, i am trying to add a prefix to a all my headers, basically i have Sales manager, Date, Amount, Profit etc, i want
1_Sales Manager
2_Date
3_Amount
4_Profit
The prefix would be combination of series of number from 1 and with delimeter "-" with the orginal text.
Please let me what would be the possible solution to it, TIA
