RemoveRows

Declaration:	TDataTable.RemoveRows (FirstRow, LastRow: integer): integer;
The method RemoveRows deletes all rows in the range from FirstRow to LastRow. The function returns the number of deleted rows if everything is OK or -1 if the FirstRow or the LastRow parameter is out of range.

Hint:

Setting both FirstRow and LastRow to zero values is a shortcut for setting FirstRow=1 and LastRow=NrOfRows, i.e. the entire data table is scanned for matching cells if both parameters are set to zero.
