Howdy,

There are a set of TeXShop macros (written in Applescript) that  
create tables or arrays and can add/delete columns. I'm not sure if  
they came with TeXShop or I added them later and I don't have the  
name of the author either. Sigh...

To add a column select the rows of the tabular and use the Add Column  
macro. It will ask for the number of the column to add before/after  
and also whether it is before/after. There will be bullets as marks  
in the column contents so you can use the macros for finding bullets  
(these come with the Command Completion files I put together) to go  
to and select each mark so it is easy to add the new data.

Will the person who wrote these macros please sand up! :-)
Hope I have permission to put them in this message.
