Installation

go get github.com/go-xlan/go-webpage

Quick Start

Basic Table Generation

package main

import (
	"fmt"
	"github.com/go-xlan/go-webpage/slice2table"
)

type User struct {
	Name string `table:"姓名"`
	Age  int    `table:"年龄"`
}

func main() {
	users := []*User{
		{Name: "Alice", Age: 25},
		{Name: "Bob", Age: 30},
	}

	htmlTable := slice2table.NewTable(users)
	fmt.Println(htmlTable)
}

Browser Output

package main

import (
	"fmt"
	"time"

	"github.com/brianvoe/gofakeit/v7"
	"github.com/go-xlan/go-webpage/firefoxopen"
	"github.com/go-xlan/go-webpage/internal/utils"
	"github.com/go-xlan/go-webpage/slice2table"
	"github.com/yyle88/must"
)

type AdminInfo struct {
	Name string
	From string
}

type GuestInfo struct {
	Name string
	From string
}

func main() {
	admins := []*AdminInfo{
		newAdminInfo(),
		newAdminInfo(),
		newAdminInfo(),
	}
	page1 := utils.NewPage("admins", slice2table.NewTable(admins))

	guests := []*GuestInfo{
		newGuestInfo(),
		newGuestInfo(),
		newGuestInfo(),
	}
	page2 := utils.NewPage("guests", slice2table.NewTable(guests))

	firefoxDraw := firefoxopen.NewFirefoxDraw()
	defer firefoxDraw.Close(time.Minute)
	firefoxDraw.ShowInNewTabs(page1, page2)
	fmt.Println("done")
}

func newAdminInfo() *AdminInfo {
	admin := &AdminInfo{}
	must.Done(gofakeit.Struct(admin))
	return admin
}

func newGuestInfo() *GuestInfo {
	guest := &GuestInfo{}
	must.Done(gofakeit.Struct(guest))
	return guest
}

Advanced Usage

Custom Tag Names

type Student struct {
	Name string `custom:"Student Name"`
	Grade int   `custom:"Grade Level"`
}

students := []*Student{
	{Name: "John", Grade: 95},
}

options := slice2table.NewOptions().WithTagName("custom")
table := slice2table.GenTable(students, options)

Single Struct Table

import "github.com/go-xlan/go-webpage/slice2table/struct2table"

user := &User{Name: "Alice", Age: 25}
table := struct2table.NewTable(user)
