I want to delete rows that have the same data in a certain column. So for example I have 5 columns in my data table and a lot of rows.
There are duplicates in ‘column 3’. I want to delete the entire row if there are duplicate codes in ‘column 3’ even though column 1,2,4 ,5 etc may not be duplicate.
Only the first data row should be there, and duplicate should get deleted.
