Sort table in report on column not displayed in the report not working

I have a table with two columns (Rowid,Rowtext) and want's to sort by rowid.
I have set the sort order to Rowid in the data tab and it displays in correct order their.
Now I add a table to my report with only column "Rowtext". Then the sort order is on "Rowtext".
How to solve the sort order so it will be Rowid in the report?

Table

Rowid, Rowtext
1 btext

2 atext

3 ctext
