The ISBLANK function returns the boolean value TRUE if the specified cell is empty and the boolean value FALSE otherwise.
ISBLANK(cell)
cell: A cell reference to a single table cell. The referenced cell can contain any value or be empty. If cell refers to more than one cell, ISBLANK will return the boolean value FALSE even if all cells are blank.
Notes
If the cell is completely blank (empty), the function returns the boolean value TRUE; otherwise it returns the boolean value FALSE. If the cell contains a space or a nonprinting character, the function will return FALSE, even though the cell appears to be blank.
