Go 之 gotable 格式化打印表格

Github 链接：GitHub - liushuochen/gotable

gotable是一个第三方库，一些复杂功能可能还不完善，但是对于简单的展示还是不成问题的。安装这些就不多说了，直接上例子吧。

示例

package main

import (
	"fmt"
	"github.com/liushuochen/gotable"
)

func main() {
	title := []string{"id", "name", "phone", "age", "sex", "description"}
	content := make([][]string, 0)
	content = append(content, []string{"1", "zhangsan", "132****2889", "25", "M", "NoDesc"})
	content = append(content, []string{"3", "lisi", "152****7873", "18", "F", "None"})
	content = append(content, []string{"5", "wangwu", "136****2908", "25", "M", "Nothing"})
	content = append(content, []string{"10", "zhaoliu", "138****5322", "15", "M", "Nothing"})
	table, err := gotable.Create(title...) // 根据title先创建空表
	if err != nil {
		fmt.Println("Create table failed:" + err.Error())
	}
	for i := 0; i < len(content); i++ {
		table.AddRow(content[i]) // 添加数据
	}

	fmt.Println(table)
	fmt.Println(table.HasColumn("name"))       // 列存在性判断
	fmt.Println("columns:", table.GetColumns()) // 获取列名（也即title）
	fmt.Println("length:", table.Length())      // 获取数据条数
	table.AddColumn("create_time")            // 添加新列
	table.Align("name", 1)               // 设置对齐方式。0 居中, 1 左对齐, 2 右对齐
	// table.CloseBorder()            // 去掉边框
	// table.OpenBorder()             // 加上边框
	// table.Clear() // 清除表格
	fmt.Println("empty?:", table.Empty())   // 为空判断
	table.ToCSVFile("test.csv")             // 写入 csv 文件
	table.ToJsonFile("test.json", 2) // 写入 json 文件
	fmt.Println(table.XML(2))             // 输出 xml
	json, err := table.JSON(2)
	if err != nil {
		fmt.Println(err)
	}
	fmt.Println(json)                           // 输出 json
}
