tablign

tablign copied to clipboard

Aligns columns in your ASCII tables.

Install with

pip install tablign

tablign in.txt out.txt

you can convert your input file

| A | 1.34|-214.1|
|CCCC | 55.534|   1131.1|

into

| A    |  1.34  | -214.1 |
| CCCC | 55.534 | 1131.1 |

Column widths are unified across the table, decimal dots are aligned, and tablign tries to be smart about column separators. Works for CSV, LaTeX, Markdown etc. By default, tablign reads from stdin and writes to stdout, so you can use pipes with tablign, too:

head -n in.txt | tablign

Usage from vim

Simply mark the table (shift-V), and type

:'<,'>:!tablign

Alternatives

GNU's column command is a mighty alternative:

column -t
