question: void commitRow ( ) { if ( rowInsretionPos == - 1 ) { rows . addElement ( currentRow ) ; } else { rows . insertElementAt ( currentRow , rowInsretionPos ++ ) ; } if ( curSegmentType != SEGMENT_TFOOT ) { bodyInsertionPos ++ ; } lastCommittedRow = currentRow ; currentRow = new Vector ( ) ; }
target:  Commits the current row. This opens a new empty row.
