# methods

|
|
|
||
|
|
``` js

## var s = table(rows, opts={})
|
||
|
|
|
||
|
|
Return a formatted table string `s` from an array of `rows` and some options
|
||
|
|
`opts`.
|
||
|
|
|
||
|
|
`rows` should be an array of arrays containing strings, numbers, or other
|
||
|
|
printable values.
|
||
|
|
|
||
|
|
options can be:
|
||
|
|
|
||
|
|
* `opts.hsep` - separator to use between columns, default `' '`
|
||
|
|
* `opts.align` - array of alignment types for each column, default `['l','l',...]`
|
||
|
|
* `opts.stringLength` - callback function to use when calculating the string length
|
||
|
|
|
||
|
|
alignment types are:
|
||
|
|
|
||
|
|
* `'l'` - left
|
||
|
|
* `'r'` - right
|
||
|
|
* `'c'` - center
|
||
|
|
* `'.'` - decimal
|

# install
|
||
|
|
|
||
|
|
With [npm](https://npmjs.org) do:
|
||
|
|
|
||
|
|
```
|
||
|
|
npm install text-table
|
||
|
|
```
|
||
|
|
|
||
|
|
# Use with ANSI-colors
|
||
|
|
|
||
|
|
Since the string length of ANSI color schemes does not equal the length
|
||
|
|
JavaScript sees internally it is necessary to pass the a custom string length
|
||
|
|
calculator during the main function call.
|
||
|
|
|
||
|
|
See the `test/ansi-colors.js` file for an example.
