I am struggling to remove duplicate rows from my data table.
Reading the datatable from an excel sheet which has 3 columns. After that I want to delete all rows where values for colum 1 AND column 2 are identical. Values of column 3 are to be ignored.
Probably an approach similiar to the following could help. However, in this solution only column1 is taken into account for duplicates: Remove duplicate rows based on a value from a single data column
