trying to insert new row in protected worksheet on a table and keep the formulas intact

I dont think you can add a new row in a table on a protected worksheet and pass down the formula from the row above to that new row?

attached sheet,
protect password cell8

here I unlock these cells

these columns are locked and hidden, they contain the formulas.

when I insert a new row, the formulas dont copy down.

Thanks Eastw00d, so after creating the new row, I must unlock the sheet and copy the formulas down into the new row?

If I choose to just hide but not lock the cells, which I presume is what you are showing? I noticed that anyone on the protected sheet can then delete the formulas from that cell in that Table. Sorry i`m still a bit lost on it.

its cool thanks Erwin for taking a look and explaining that, at least I know the difficulties at the moment.
