Hi
You need to create a internal table same as you have in table control.and work area.
loop at internal table where you have data into new work area.
\
WHEN'MOVE'.
"Retrieving record selected
LOOPAT it1 INTO wa1 WHERE MARK = 'X'.
"Making records being not selected
CLEAR wa1-MARK.
"Moving record to destination table
APPEND wa1 TO it2.
ENDLOOP.
