You want to use it as a header for what? I'm going to guess as a query because you want to export it and you want it to have "nice" column names that users like. You don't need to change column names to link tables/queries to each other. Just draw the appropriate join lines or if you are creating append queries, select the columns you want as the source. Then type in the destination names. When the names are the same, Access nicely fills in the target names but when they are different, Access has no clue how to match the names so you have to do it.
In queries, you can alias any column name.
Select col1 As cola, col2 as colb, col3 as colc, etc.
So you would have to write code to read the headings table and then write SQL to select the data from some other table and alias the column names.
