In Row Filter node chose option Include rows by number. Then define your First row number (which is by default 1) and under Flow Variables tab define RowRangeEnd parameter. This parameter is Integer type so in your Table Creator node your column1 should be type Integer instead of String. In configuration window you will have notification that RowRangeEnd is controlled by a parameter. Here are printscreens:
I have checked your workflow and not completely sure what are you trying to accomplish but anyways hope this will help you
