Allow Adding New Row To A Table When Worksheet Protected

I have A TABLE (Named Table1) and some columns filled by formula. (Like E,F,G,H columns) When I protect the worksheet E,F,G,H columns are locked, but A,B,C,D columns are UNLOCKED. When is sheet PROTECTED , If I add a row bottom of Table1, does NOT automatically fill the E,F,G,H columns and Table1 range does not expanding. But, if UNPROTECTED, it's OK. when add a row bottom of Table1, automatically fill all columns with formula and table range is expanding aotomatically with new row.

When sheet is PROTECTED , How can I allow, to add a row and aouto fill all columns like unprotected.

And I want to protect sheet in any case, after allowing to add row.

I need a macro code to do this.
