Package table provides a convenient way to generate tabular output of any data, primarily useful for CLI tools.
|
||
|
|
|
||
|
|
## Features
|
||
|
|
|
||
|
|
- Accepts all data types (`string`, `int`, `interface{}`, everything!) and will use the `String() string` method of a type if available.
|
||
|
|
- Can specify custom formatting for the header and first column cells for better readability.
|
||
|
|
- Columns are left-aligned and sized to fit the data, with customizable padding.
|
||
|
|
- The printed output can be sent to any `io.Writer`, defaulting to `os.Stdout`.
|
||
|
|
- Built to an interface, so you can roll your own `Table` implementation.
|
||
|
|
- Works well with ANSI colors ([fatih/color](https://github.com/fatih/color) in the example)!
|
||
|
|
- Can provide a custom `WidthFunc` to accomodate multi- and zero-width characters (such as [runewidth](https://github.com/mattn/go-runewidth))
|
||
