Gotabulate - Easily pretty-print tabular data
Summary
Go-Tabulate - Generic Go Library for easy pretty-printing of tabular data.
Installation
go get github.com/bndr/gotabulate
Description
Supported data types:
- 2D Array of
Int,Int64,Float64,String,interface{} - Map of
String,interface{}(Keys will be used as header)
Usage
// Create Some Fake Rows
row_1 := []interface{}{"john", 20, "ready"}
row_2 := []interface{}{"bndr", 23, "ready"}
// Create an object from 2D interface array
t := gotabulate.Create([][]interface{}{row_1, row_2})
// Set the Headers (optional)
t.SetHeaders([]string{"age", "status"})
// Set the Empty String (optional)
t.SetEmptyString("None")
// Set Align (Optional)
t.SetAlign("right")
// Print the result: grid, or simple
fmt.Println(t.Render("grid"))
+---------+--------+-----------+
| | age | status |
+=========+========+===========+
| john | 20 | ready |
+---------+--------+-----------+
| bndr | 23 | ready |
+---------+--------+-----------+
Example with String
// Some Strings
string_1 := []string{"TV", "1000$", "Sold"}
string_2 := []string{"PC", "50%", "on Hold"}
// Create Object
tabulate := gotabulate.Create([][]string{string_1, string_2})
// Set Headers
tabulate.SetHeaders([]string{"Type", "Cost", "Status"})
// Render
fmt.Println(tabulate.Render("simple"))
--------- ---------- ------------
Type Cost Status
--------- ---------- ------------
TV 1000$ Sold
PC 50% on Hold
--------- ---------- ------------
Example with String Wrapping
tabulate := gotabulate.Create([][]string{[]string{"Lorem ipsum dolor sit amet, consectetur adipiscing elit. Vivamus laoreet vestibulum pretium. Nulla et ornare elit. Cum sociis natoque penatibus et magnis",
"Vivamus laoreet vestibulum pretium. Nulla et ornare elit. Cum sociis natoque penatibus et magnis", "zzLorem ipsum", " test", "test"}, []string{"Lorem ipsum dolor sit amet, consectetur adipiscing elit. Vivamus laoreet vestibulum pretium. Nulla et ornare elit. Cum sociis natoque penatibus et magnis",
"Vivamus laoreet vestibulum pretium. Nulla et ornare elit. Cum sociis natoque penatibus et magnis", "zzLorem ipsum", " test", "test"}, STRING_ARRAY, []string{"Lorem ipsum dolor sit amet, consectetur adipiscing elit. Vivamus laoreet vestibulum pretium. Nulla et ornare elit. Cum sociis natoque penatibus et magnis",
"Vivamus laoreet vestibulum pretium. Nulla et ornare elit. Cum sociis natoque penatibus et magnis", "zzLorem ipsum", " test", "test"}, STRING_ARRAY})
tabulate.SetHeaders([]string{"Header 1", "header 2", "header 3", "header 4"})
// Set Max Cell Size
tabulate.SetMaxCellSize(16)
// Turn On String Wrapping
tabulate.SetWrapStrings(true)
// Render the table
fmt.Println(tabulate.Render("grid"))
