string,int,interface{}, everything!) and will use theString() stringmethod 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 toos.Stdout. - Built to an interface, so you can roll your own
Tableimplementation. - Works well with ANSI colors (fatih/color in the example)!
