Hi @Ajay1998,
welcome to our community!
It is not possible to simply exclude one row. What you could possibly do is to set a component filter on the column containing the values A, B, C, D, NULL. In case you always want to exclude NULL, your component filter looks like this:

FILTER Table.Column Name != NULL

Unfortunately, it is currently not possible to add a total row to the table. You could add a Number component and sum up your values respectivly.
Best,
Justin
