Cell precedent for Table's column header rename in structure reference should not be deemed as a region precedent

Related to KEIKAI-396

In an Excel Table(A1:B5), 2 columns, 4 rows with column header.

In column2(B2:B5), we enter "=SUM([Column1])"

Then the Range.getPrecedents() of B2 should be "A2:A5".

but current result is "A2:A5, A1" which is not correct.
