I was helping a colleague build a formula inside of a structured table. Part of the formula included a reference to a cell in a different column in the same row like [@[SiteID]]. When we copied that formula to one column over to the right, still in the same table, the reference of [@[SiteID]] changed to one column over to the right of it like [@[Address]]. Throughout the formula it acted the same as if we used relative referencing in a regular formula. It's as we we had the formula '=A1' in cell C1 and then copied it to D1 to result in '=B1'. I didn't even know that Excel could do relative referencing within a structured table. How did that happen?
