Note that columns J and K are different therefore I cannot just see if there are duplicated rows and remove them.
To do this, I would like to read the range of columns A:G in both tables, get the rows indexes where there are matches then use that row index to remove the entire row from table b.
Please could you advise how I would get the row indexes of the matches? I attempted to use the lookup activity but that seems to only look at one column and not a range?
