[1mcolumn [ [4m[22mColumn[24m [4m...[24m [1m] < [4m[22mtableorlist[0m
|

|

The command [1mcolumn [22mreads [4mtableorlist[24m and writes a new table (or list) that
|
||
consists of each [4mColumn[24m, in the order you list them on the command line.
|
||
|
||
If you give a column name that is not one of the columns for [4mtableorlist[24m,
|
||
[1mcolumn [22mcreates a new column with that name, in that location, and leaves it
|
||
empty. This lets you to create new columns. If you want to compute a col‐
|
||
umn that does not exist, use this [1mcolumn [22mfacility to create it, then use
|
||
the [1mcompute [22mcommand to compute it. However, if you misspell a column name,
