fScan Reference Manual, Chapter 2 (CmdLineOptions): table_config
usage: -table configure TBLNAME [FLAG] COLNAME [TYPE] [COLNUM] … [COLNAMEx TYPE COLNUM]
The CONFIGURE option can be used to re-configure an existing table (or create a new empty table). It is intended for adding column names, adding whole columns, moving existing columns, or removing columns. Columns to be modified are specified as triplets of “name type colnum” (of these only the name is required). Multiple column specifications can be combined in a single command.
If column NAME exists it is modified to TYPE and moved, if necessary, to column COLNUM.
Otherwise, column NAME of type TYPE is added as COLNUM (COLNUM=0 or omitted, means last column).
TYPE can be int, float, or text (default is text).
