In the "Structure" tab of the Firefox "SQLite Manager" add-on, you can
export the schema for a table to a text file [1], then edit the text
file and feed it back into the database with the menu item Database /
Import, or with the sqlite command line tool [2].
[1] can be compared with .dump in the sqlite command line tool,
as in echo .dump | sqlite3 yourdbfile >schemafile.sql
edit schemafile.sql to reflect your modifications
[2] sqlite3 yourdbile <schemafile.sql
Hope this helps
