Options

Command	Result
-a	specify alignment (left or right) - see examples below
-c	specify which columns to print
-h	print help message
--markdown	print as markdown
--latex	print as latex table
--numeric [c1:d1] [c2:d2] ...	specify decimal numbers for chosen numeric columns (c for column, d for digits)
--header	add header decoration around the first line
-s 'char'	file is delimited by char (instead of comma), tab for tab

Alignment example

There are three options for specifying alignment. One can use l or r for aligning all cells to the left or right, respectively. One can also specify a distinct alignment option for each column. Then the number of options will need to match the number of columns.

» csvprint imdb.csv -a l r r
