I want to know the row number of Currentrow in for Each Row in Data table

Hi,

You can use the index property of for each row in datatable activity.
When there are no specific characters in the column A you can store the value of index in a variable.
The image shows the properties panel of the UiPath "For Each Row" activity, highlighting the output index field in yellow. (Captioned by AI)

Thanks,
