I have 6 map tables, each containing polygons for different areas. These tables (call them A1 to A6) contain various data columns. I want to save the polygon information in each, but delete all the data columns and then add the same 40 columns to each - the end result being 6 tables with the same structure.
My attempt at the process was to copy table A1, delete un-needed columns and add the 40 new ones in table maintenance. I then deleted all the records, assuming this would give me a base (template) table with no data, but the table structure I required. I then copied table A1 to B1 and removed all the un-needed columns and then appended B1 to a copy of my template. This seemed to work OK (all records and data copied), but the polygon info didn't seem to. Mapping the new table produced just one short straight line. I thought it might have been a projection problem, but all tables had the same projection.
Is there a simple way to do what I'm trying to do? If it was Access, I'd just open up the source table in design view and copy the fields and paste to the new table, but Mapinfo doesn't seem to allow cut & paste in the Table Maintenance window.
TIA for any help that can be offered.
