Help with shifting table columns

[flashkid10]

So, I have a main excel doc with a (smart?) table on it,and I’m constantly add more columns into it. this wouldn't be a problem ifother excel files didn't pull data from the main doc. whenever I add in anew column, it breaks all the formulas on the other doc. tables have specialname for columns (Data[@Tags], Data is table name, tag is column name), isthere a way to use this in a different sheet?<o></o>
