> In which case columns will have different sizes? Could you give an example?
At the beginning, I tried to do expression evaluation on some incomplete blocks (specifically, some columns are empty, but the columns involved in the expression are complete), such as `vcast_expr`, pass in `block.rows ()` can not get the correct result.
Later I confirmed that expression evaluation should not be performed on incomplete blocks, so this `pull-request` was changed to resize the `param column` passed in `vcast_expr` to ensure that each column in the block is always the same size.
