How to read a range with unknown row numbers

I’m really new to UiPath and I need to copy some data from an excel sheet. The columns are fixed from A-F but the number of rows will vary. How do I put this data into a data table? I tried read range with just the columns A:F, but i think that copied all the rows those columns had, not the data specifically.
Any tips / solutions?

@zham667 first read the excel normally using read range activity (for example dt will be the output).
Then again read the excel using read range activity with range as
Above range will give you required output
