| # | FIRST NAME | LAST NAME | SALARY | |
+-----+------------+-----------+--------+-----------------------------+
| 1 | Arya | Stark | 3000 | |
| 20 | Jon | Snow | 2000 | You know nothing, Jon Snow! |

A demonstration of all the capabilities can be found here: ../cmd/demo-table
If you want very specific examples, read ahead.
All the examples below are going to start with the following block, although
nothing except a single Row is mandatory for the Render() function to render
something:
package main
import (
"os"
"github.com/jedib0t/go-pretty/table"
)
func main() {
t := table.NewWriter()
t.SetOutputMirror(os.Stdout)
t.AppendHeader(table.Row{"#", "First Name", "Last Name", "Salary"})
t.AppendRows([]table.Row{
{1, "Arya", "Stark", 3000},
{20, "Jon", "Snow", 2000, "You know nothing, Jon Snow!"},
})
t.AppendRow([]interface{}{300, "Tyrion", "Lannister", 5000})
t.AppendFooter(table.Row{"", "", "Total", 10000})
t.Render()
}Running the above will result in:
+-----+------------+-----------+--------+-----------------------------+
| # | FIRST NAME | LAST NAME | SALARY | |
+-----+------------+-----------+--------+-----------------------------+
| 1 | Arya | Stark | 3000 | |
| 20 | Jon | Snow | 2000 | You know nothing, Jon Snow! |
| 300 | Tyrion | Lannister | 5000 | |
+-----+------------+-----------+--------+-----------------------------+
| | | TOTAL | 10000 | |
+-----+------------+-----------+--------+-----------------------------+
You can customize almost every single thing about the table above. The previous
example just defaulted to StyleDefault during Render(). You can use a
ready-to-use style (as in style.go) or customize it as you want.
Table comes with a bunch of ready-to-use Styles that make the table look really good. Set or Change the style using:
t.SetStyle(table.StyleLight)
t.Render()to get:
┌─────┬────────────┬───────────┬────────┬─────────────────────────────┐
│ # │ FIRST NAME │ LAST NAME │ SALARY │ │
├─────┼────────────┼───────────┼────────┼─────────────────────────────┤
│ 1 │ Arya │ Stark │ 3000 │ │
│ 20 │ Jon │ Snow │ 2000 │ You know nothing, Jon Snow! │
│ 300 │ Tyrion │ Lannister │ 5000 │ │
├─────┼────────────┼───────────┼────────┼─────────────────────────────┤
│ │ │ TOTAL │ 10000 │ │
└─────┴────────────┴───────────┴────────┴─────────────────────────────┘
Or if you want to use a full-color mode, and don't care for boxes, use:
t.SetStyle(table.StyleColoredBright)
t.Render()to get:
You can also roll your own style:
t.SetStyle(table.Style{
Name: "myNewStyle",
Box: table.BoxStyle{
BottomLeft: "\\",
BottomRight: "/",
BottomSeparator: "v",
Left: "[",
LeftSeparator: "{",
MiddleHorizontal: "-",
MiddleSeparator: "+",
MiddleVertical: "|",
PaddingLeft: "<",
PaddingRight: ">",
Right: "]",
RightSeparator: "}",
TopLeft: "(",
TopRight: ")",
TopSeparator: "^",
UnfinishedRow: " ~~~",
},
Color: table.ColorOptions{
AutoIndexColumn: nil,
FirstColumn: nil,
Footer: text.Colors{text.BgCyan, text.FgBlack},
Header: text.Colors{text.BgHiCyan, text.FgBlack},
Row: text.Colors{text.BgHiWhite, text.FgBlack},
RowAlternate: text.Colors{text.BgWhite, text.FgBlack},
},
Format: table.FormatOptions{
Footer: text.FormatUpper,
Header: text.FormatUpper,
Row: text.FormatDefault,
},
Options: table.Options{
DrawBorder: true,
SeparateColumns: true,
SeparateFooter: true,
SeparateHeader: true,
SeparateRows: false,
},
})Or you can use one of the ready-to-use Styles, and just make a few tweaks:
t.SetStyle(table.StyleLight)
t.Style().Color.Header = text.Colors{text.BgHiCyan, text.FgBlack}
t.Style().Format.Footer = text.FormatLower
t.Style().Options.DrawBorder = falseYou can limit then number of lines rendered in a single "Page". This logic can handle rows with multiple lines too. Here is a simple example:
t.SetPageSize(1)
t.Render()to get:
+-----+------------+-----------+--------+-----------------------------+
| # | FIRST NAME | LAST NAME | SALARY | |
+-----+------------+-----------+--------+-----------------------------+
| 1 | Arya | Stark | 3000 | |
+-----+------------+-----------+--------+-----------------------------+
| | | TOTAL | 10000 | |
+-----+------------+-----------+--------+-----------------------------+
+-----+------------+-----------+--------+-----------------------------+
| # | FIRST NAME | LAST NAME | SALARY | |
+-----+------------+-----------+--------+-----------------------------+
| 20 | Jon | Snow | 2000 | You know nothing, Jon Snow! |
+-----+------------+-----------+--------+-----------------------------+
| | | TOTAL | 10000 | |
+-----+------------+-----------+--------+-----------------------------+
+-----+------------+-----------+--------+-----------------------------+
| # | FIRST NAME | LAST NAME | SALARY | |
+-----+------------+-----------+--------+-----------------------------+
| 300 | Tyrion | Lannister | 5000 | |
+-----+------------+-----------+--------+-----------------------------+
| | | TOTAL | 10000 | |
+-----+------------+-----------+--------+-----------------------------+
You can restrict the maximum (text) width for a Row:
t.SetAllowedRowLength(50)
t.Render()to get:
+-----+------------+-----------+--------+------- ~
| # | FIRST NAME | LAST NAME | SALARY | ~
+-----+------------+-----------+--------+------- ~
| 1 | Arya | Stark | 3000 | ~
| 20 | Jon | Snow | 2000 | You kn ~
| 300 | Tyrion | Lannister | 5000 | ~
+-----+------------+-----------+--------+------- ~
| | | TOTAL | 10000 | ~
+-----+------------+-----------+--------+------- ~
You can control a lot of things about individual cells/columns which overrides
global properties/styles using the SetColumnConfig() interface:
- Alignment (horizontal & vertical)
- Colorization
- Transform individual cells based on the content
- Width (minimum & maximum)
nameTransformer := text.Transformer(func(val interface{}) string {
return text.Bold.Sprint(val)
})
t.SetColumnConfigs([]ColumnConfig{
{
Name: "First Name",
Align: text.AlignLeft,
AlignFooter: text.AlignLeft,
AlignHeader: text.AlignLeft,
Colors: text.Colors{text.BgBlack, text.FgRed},
ColorsHeader: text.Colors{text.BgRed, text.FgBlack, text.Bold},
ColorsFooter: text.Colors{text.BgRed, text.FgBlack},
Transformer: nameTransformer,
TransformerFooter: nameTransformer,
TransformerHeader: nameTransformer,
VAlign: text.VAlignMiddle,
VAlignFooter: text.VAlignTop,
VAlignHeader: text.VAlignBottom,
WidthMin: 6,
WidthMax: 64,
}
})Tables can be rendered in other common formats such as:
t.RenderCSV()to get:
,First Name,Last Name,Salary,
1,Arya,Stark,3000,
20,Jon,Snow,2000,"You know nothing\, Jon Snow!"
300,Tyrion,Lannister,5000,
,,Total,10000,
t.RenderHTML()to get:
