If you're trying to get all the data out of a table (data, not schema) then you can use the ?a=ImportExport screen to export an entire table of data to CSV format.
If you're trying to get all the schema out of a table, I recommend using the Application Documentor in the Exchange published by Ryan Pflederer; which is a great tool and does the work in minutes.
If you're trying to backup your entire Application Data content, I recommend using the QuNect.com QuNect Backup tool which will download ALL your data form ALL your tables into CSV format.
