I have a couple of feature request that I would humbly ask if you'd be willing to add...
When used with -t, include an option for -y to specify the sort type:
-y c will sort the table output by colums
-y r will sort the table output by rows (default)
When used with -i, include an option for -o to specify the sort order:
-o a will sort the data in ascending alphabetical order before generating the output
-o z will sort the data in descending alphabetical order before generating the output
Omitting -o will leave the data as it's sorted in the input file.
