Installation is simple as go get github.com/olekukonko/tablewriter #### Features - Automatic Padding - Support Multiple Lines - Supports Alignment - Support Custom Separators - Automatic Alignment of numbers & percentage - Write directly to http , file etc via `io.Writer` - Read directly from CSV file - Optional row line via `SetRowLine` - Normalise table header - Make CSV Headers optional - Enable or disable table border - Set custom footer support - Optional identical cells merging - Set custom caption - Optional reflowing of paragrpahs in multi-line cells. #### Example 1 - Basic ```go data := [][]string{ []string{"A", "The Good", "500"}, []string{"B", "The Very very Bad Man", "288"}, []string{"C", "The Ugly", "120"}, []string{"D", "The Gopher", "800"}, } table := tablewriter.NewWriter(os.Stdout) table.SetHeader([]string{"Name", "Sign", "Rating"}) for _, v := range data { table.Append(v) } table.Render() // Send output ``` ##### Output 1 ``` +------+-----------------------+--------+ | NAME | SIGN | RATING | +------+-----------------------+--------+ | A | The Good | 500 | | B | The Very very Bad Man | 288 | | C | The Ugly | 120 | | D | The Gopher | 800 | +------+-----------------------+--------+ ``` #### Example 2 - Without Border / Footer / Bulk Append ```go data := [][]string{ []string{"1/1/2014", "Domain name", "2233", "$10.98"}, []string{"1/1/2014", "January Hosting", "2233", "$54.95"}, []string{"1/4/2014", "February Hosting", "2233", "$51.00"}, []string{"1/4/2014", "February Extra Bandwidth", "2233", "$30.00"}, } table := tablewriter.NewWriter(os.Stdout) table.SetHeader([]string{"Date", "Description", "CV2", "Amount"}) table.SetFooter([]string{"", "", "Total", "$146.93"}) // Add Footer table.SetBorder(false) // Set Border to false table.AppendBulk(data) // Add Bulk Data table.Render() ``` ##### Output 2 ``` DATE | DESCRIPTION | CV2 | AMOUNT -----------+--------------------------+-------+---------- 1/1/2014 | Domain name | 2233 | $10.98 1/1/2014 | January Hosting | 2233 | $54.95 1/4/2014 | February Hosting | 2233 | $51.00 1/4/2014 | February Extra Bandwidth | 2233 | $30.00 -----------+--------------------------+-------+---------- TOTAL | $146 93 --------+---------- ``` #### Example 3 - CSV ```go table, _ := tablewriter.NewCSV(os.Stdout, "testdata/test_info.csv", true) table.SetAlignment(tablewriter.ALIGN_LEFT) // Set Alignment table.Render() ``` ##### Output 3 ``` +----------+--------------+------+-----+---------+----------------+ | FIELD | TYPE | NULL | KEY | DEFAULT | EXTRA | +----------+--------------+------+-----+---------+----------------+ | user_id | smallint(5) | NO | PRI | NULL | auto_increment | | username | varchar(10) | NO | | NULL | | | password | varchar(100) | NO | | NULL | | +----------+--------------+------+-----+---------+----------------+ ``` #### Example 4 - Custom Separator ```go table, _ := tablewriter.NewCSV(os.Stdout, "testdata/test.csv", true) table.SetRowLine(true) // Enable row line // Change table lines table.SetCenterSeparator("*") table.SetColumnSeparator("╪") table.SetRowSeparator("-") table.SetAlignment(tablewriter.ALIGN_LEFT) table.Render() ``` ##### Output 4 ``` *------------*-----------*---------* ╪ FIRST NAME ╪ LAST NAME ╪ SSN ╪ *------------*-----------*---------* ╪ John ╪ Barry ╪ 123456 ╪ *------------*-----------*---------* ╪ Kathy ╪ Smith ╪ 687987 ╪ *------------*-----------*---------* ╪ Bob ╪ McCornick ╪ 3979870 ╪ *------------*-----------*---------* ``` #### Example 5 - Markdown Format ```go data := [][]string{ []string{"1/1/2014", "Domain name", "2233", "$10.98"}, []string{"1/1/2014", "January Hosting", "2233", "$54.95"}, []string{"1/4/2014", "February Hosting", "2233", "$51.00"}, []string{"1/4/2014", "February Extra Bandwidth", "2233", "$30.00"}, } table := tablewriter.NewWriter(os.Stdout) table.SetHeader([]string{"Date", "Description", "CV2", "Amount"}) table.SetBorders(tablewriter.Border{Left: true, Top: false, Right: true, Bottom: false}) table.SetCenterSeparator("|") table.AppendBulk(data) // Add Bulk Data table.Render() ``` ##### Output 5 ``` | DATE | DESCRIPTION | CV2 | AMOUNT | |----------|--------------------------|------|--------| | 1/1/2014 | Domain name | 2233 | $10.98 | | 1/1/2014 | January Hosting | 2233 | $54.95 | | 1/4/2014 | February Hosting | 2233 | $51.00 | | 1/4/2014 | February Extra Bandwidth | 2233 | $30.00 | ``` #### Example 6 -

7 Table Cells with Color Individual Cell Colors from `func Rich` take precedence over Column Colors ```go data := [][]string{ []string{"Test1Merge", "HelloCol2 - 1", "HelloCol3 - 1", "HelloCol4 - 1"}, []string{"Test1Merge", "HelloCol2 - 2", "HelloCol3 - 2", "HelloCol4 - 2"}, []string{"Test1Merge", "HelloCol2 - 3", "HelloCol3 - 3", "HelloCol4 - 3"}, []string{"Test2Merge", "HelloCol2 - 4", "HelloCol3 - 4", "HelloCol4 - 4"}, []string{"Test2Merge", "HelloCol2 -

COLOR1", "HelloCol3 - COLOR1", "HelloCol4 - COLOR1"} colorData2 := []string{"TestCOLOR2Merge", "HelloCol2 - COLOR2", "HelloCol3 - COLOR2", "HelloCol4 - COLOR2"} for i, row := range data { if i == 4 { table.Rich(colorData1, []tablewriter.Colors{tablewriter.Colors{}, tablewriter.Colors{tablewriter.Normal, tablewriter.FgCyanColor}, tablewriter.Colors{tablewriter.Bold, tablewriter.FgWhiteColor}, tablewriter.Colors{}}) table.Rich(colorData2, []tablewriter.Colors{tablewriter.Colors{tablewriter.Normal, tablewriter.FgMagentaColor}, tablewriter.Colors{}, tablewriter.Colors{tablewriter.Bold, tablewriter.BgRedColor}, tablewriter.Colors{tablewriter.FgHiGreenColor, tablewriter.Italic, tablewriter.BgHiCyanColor}}) } table.Append(row) } table.SetAutoMergeCells(true) table.Render() ``` ##### Table cells with color Output ![Table cells with Color](https://user-images.githubusercontent.com/9064687/63969376-bcd88d80-ca6f-11e9-9466-c3d954700b25.png) #### Example 8 - Set table caption ```go data := [][]string{ []string{"A", "The Good", "500"}, []string{"B", "The Very very Bad Man", "288"}, []string{"C", "The Ugly", "120"}, []string{"D", "The Gopher", "800"}, } table := tablewriter.NewWriter(os.Stdout) table.SetHeader([]string{"Name", "Sign", "Rating"}) table.SetCaption(true, "Movie ratings.") for _, v := range data { table.Append(v) } table.Render() // Send output ``` Note: Caption text will wrap with total width of rendered table. ##### Output 7 ``` +------+-----------------------+--------+ | NAME | SIGN | RATING | +------+-----------------------+--------+ | A | The Good | 500 | | B | The Very very Bad Man | 288 | | C | The Ugly | 120 | | D | The Gopher | 800 | +------+-----------------------+--------+ Movie ratings. ``` #### Example 8 - Set NoWhiteSpace and TablePadding option ```go data := [][]string{ {"node1.example.com", "Ready", "compute", "1.11"}, {"node2.example.com", "Ready", "compute", "1.11"}, {"node3.example.com", "Ready", "compute", "1.11"}, {"node4.example.com", "NotReady", "compute", "1.11"}, } table := tablewriter.NewWriter(os.Stdout) table.SetHeader([]string{"Name", "Status", "Role", "Version"}) table.SetAutoWrapText(false) table.SetAutoFormatHeaders(true) table.SetHeaderAlignment(ALIGN_LEFT) table.SetAlignment(ALIGN_LEFT) table.SetCenterSeparator("") table.SetColumnSeparator("") table.SetRowSeparator("") table.SetHeaderLine(false) table.SetBorder(false) table.SetTablePadding("\t") // pad with tabs table.SetNoWhiteSpace(true) table.AppendBulk(data) // Add Bulk Data table.Render() ``` ##### Output 8 ``` NAME STATUS ROLE VERSION node1.example.com Ready compute 1.11 node2.example.com Ready compute 1.11 node3.example.com Ready compute 1.11 node4.example.com NotReady compute 1.11 ``` #### Render table into a string Instead of rendering the table to `io.Stdout` you can also render it into a string. Go 1.10 introduced the `strings.Builder` type which implements the `io.Writer` interface and can therefore be used for this task. Example: ```go package main import ( "strings" "fmt" "github.com/olekukonko/tablewriter" ) func main() { tableString := &strings.Builder{} table := tablewriter.NewWriter(tableString) /* * Code to fill the table */ table.Render() fmt.Println(tableString.String()) } ``` #### TODO - ~~Import Directly from CSV~~ - `done` - ~~Support for `SetFooter`~~ - `done` - ~~Support for `SetBorder`~~ - `done` - ~~Support table with uneven rows~~ - `done` - ~~Support custom alignment~~ - General Improvement & Optimisation - `NewHTML` Parse table from HTML
