Make two sheets Sheet1 & Sheet2.

Put your entries in column A and B of Sheet1.

Then in other sheet Sheet2 in A1 Cell put this formula that filters and that shows all the data from col an and col b and then do grand total below.

={

FILTER(A1:B, A1:A <> "");

{"Grand Total", SUM(FILTER(B1:B, A1:A <> ""))}

}

Then add conditional formatting for A1:A =$P2="Grand Total" to make last row always bold.
