I can do it in excel 2007.

I have a tab delimited text file that I import into Excel 2003. The fields
import correcly. Next I need to create a table for the data. If I go to the
Data menu and then select table, I am presented With a "Row input cell" and
"Column input cell". I have no idea what to input here. If I use Excel 2007
the same steps then ask me "What is the data for your table" and I then
select all the columns & rows with data. I tried selecting all the rows for
the "Row input cell" and all the columns for "Column input cell" but I get an
error that says "Input cell reference is not valid".

The reason I want to create a table is for sorting purposes.
