Tool for aligning data in columns
tabulate-1.0.2 is not a library.

tabulate

Align data in columns using heuristics to find suitable column sizes that minimize the amount of wasted space. Useful for files like access logs where some lines have columns that are much larger than than the rest of the lines.

$ cat input.txt
aaa bbb ccc
a   b   c
aaaaaaaaaaaaaaaaaaaaaaa bb cc
aaaaa b ccccc
aaa bb ccc

USAGE:
    tabulate [OPTIONS]

OPTIONS:
        --column-info
            Print information about the columns

    -c, --compress-cols <RATIO>
            Control how much columns are compressed. Set to 0 to disable column
            compression, i.e. columns are sized to fit the largest value [default:
            1.0]
    -d, --delimiter <DELIM>
            Use characters of DELIM as column delimiters [default: " \t"]

    -n, --estimate-count <N>
            Estimate column sizes from the first N lines [default: 1000]

    -x, --exclude <LIST>
            Select which columns should be excluded from the output. This option
            takes precedence over --include
    -h, --help
            Prints help information

    -i, --include <LIST>
            Select which columns to include in the output

    -s, --strict
            Parse columns as strictly being delimited by a single delimiter

    -t, --truncate <LIST>
            Truncate data that does not fit in a column. Takes an optional list of
            columns that should be truncated. If no LIST is given all columns are
            truncated
    -V, --version
            Prints version information


LIST should be a comma-separated list of ranges. Each range should be of one of the
following forms:

  N       N'th column, starting at 1
  N-      from N'th column to end of line
  N-M     from N'th to M'th column
  -M      from first to M'th column
