vue封装表格组件,左边固定列右边滑动,可排序可操作

本文主要是介绍vue封装表格组件,左边固定列右边滑动,可排序可操作,对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!

 如标题,效果如下图:

 我做的是移动端,表格太长,所以做左边固定列右边滑动,上图右边显示动态箭头是让用户知道表格可以滑动。

表格的思路:

  • 写两个table
  • 一个是整体的table,外面的div保持宽度固定,内部的table宽度大于外部才能滚动;
  • 一个是左边固定列,这个固定position:absolute在左边,就是盖在大table上面;

下面table组件

// table.vue
<template>
    <div>
        <div class="product-list">
            <!-- 可滑动的全表格 -->
            <div class="table-scroll-container" ref="tableScrollBox">
                <table class="table-scroll" border="0" cellpadding="0" cellspacing="0">
                    <tbody class="tbody">
                        <tr class="title-tr">
                            <th class="ta-c" v-for="(item,index) in headData" :key="index" :class="{ 'first-col': index == 0 }">
                                {{ item.name }}
                            </th>
                        </tr>
                        <template>
                            <tr class="tbody-content" v-for="(item, index) in bodyData" :key="index">
                                <td
                                    class="info-box" 
                                    v-for="(colItem, colIndex) in headData"
                                    :class="[{ 'first-col clearfix': colIndex == 0 },colItem.class]">
                                        {{ item[colItem.prop] }}
                                </td>
                            </tr>
                        </template>
                    </tbody>
                </table>
            </div>
            <!-- 覆盖的左侧表格 -->
            <div class="table-left-container" v-if="isTableLeft">
                <table class="table-left" :class="{ 'norem-table-fixed-left': isLeft }" border="0" cellpadding="0" cellspacing="0">
                    <tbody class="tbody">
                        <tr class="title-tr">
                            <th class="first-col">{{ headData[0].name }}</th>
                        </tr>
                        <template>
                            <tr class="tbody-content" v-for="(item, index) in bodyData" :key="index">
                                <td class="info-box" v-if="headData[0].prop">{{ item[headData[0].prop] }}</td>
                            </tr>
                        </template>
                    </tbody>
                </table>
            </div>
        </div>
        <!-- 动态箭头 bodyData没有数据就不显示 -->
        <div class="arrow" v-if="bodyData.length != 0 && !arrow_left"></div>
    </div>
</template>

<script>
    export default {
        props: {
            // 表头内容
            headData: {
                type: Array,
                default: () => []
            },
            // 表格内容
            bodyData: {
                type: Array,
                default: () => []
            },
            // 是否要固定左边列

            arrow_left: {
                type: Boolean,
                default: () => false
            }
        },
        data() {
            return {
                isLeft: false,
            };
        },
        mounted() {
            //监听表格滚动,表格滚动到左边0时候去掉左边固定列的阴影,滚动到大于0时候才显示左边固定列的列
            this.$refs.tableScrollBox.addEventListener(
                "scroll",
                () => {
                    this.$refs.tableScrollBox.scrollLeft
                    if(this.$refs.tableScrollBox.scrollLeft > 0){
                        this.isLeft = true;
                    }else{
                        this.isLeft = false;
                    }
                },
                true
            );
        },
    };
</script>

// 动态箭头
<style scoped lang="less">
    .arrow {
        display: block;
        width: 10px;
        height: 10px;
        position: fixed;
        top: 50%;
        right: 0;
        margin-left: -11px;
        border: 3px solid transparent;

            transform:translate(-10px, 0) rotate(313deg)
        }
    }
</style>

下面需要表格组件的vue文件

// userList.vue
<template>
    <div>
        <tableLocked 
            :headData="tableHead" 
            :bodyData="tableBody" 
            :isTableLeft='true'>
        </tableLocked>
    </div>
</template>

<script>
    import tableLocked from './tableLocked.vue'
    export default {
        data() {
            return {
                 // table表头
                tableHead: [
                    {
                        name: '账号',
                        prop: 'user_name'
                    },
                    {
                        name: '内容1',
                        prop: 'user1'
                    },
                    {
                        name: '内容2',
                        prop: 'user2'
                    },
                    {
                        name: '内容3',
                        prop: 'user3',
                    },
                    {
                        name: '内容4',
                        prop: 'user4',
                    },
                    {
                        name: '内容5',
                        prop: 'user5'
                    },
                    {
                        name: '操作',
                        prop: ''
                    }
                ],
                // table内容
                tableBody: [],
            }
        },
        components: {
            tableLocked
        }
    }
</script>

排序的思路:

  • 给需要排序的表头多两个字段,一个显示,一个传值(Asc/Desc)
  • 排序事件把Asc/Desc和该表头的值给父组件传过去

userList.vue:需要排序的表头添加两个字段

table.vue组件:添加排序的元素

<span class="sort" v-if="item.isSort" @click="onSort(item)">
    <i class="up" :class="{ active: item.SortType == 'Asc' }"></i>
    <i class="down" :class="{ active: item.SortType == 'Desc' }"></i>
</span>
methods: {
    // 排序
    onSort(item){
        for(var i = 0; i < this.headData.length; i++){
            if(this.headData[i].prop != item.prop){
                this.headData[i].SortType = ''
            }
        }
        // 避免重复请求
        if(item.SortType == ''){
            item.SortType = 'Asc'
        }else if(item.SortType == 'Asc'){
            item.SortType = 'Desc'
        }else{
            item.SortType = ''
        }
        // 把该参数给父组件过去,并触发父组件排序事件
        this.$emit('goSort', item)
    }
},

 userList.vue:排序事件中获取该值并请求/逻辑

methods: {
    // 排序
    sortClick (item){
        console.log(item)
        // 逻辑
        // ...
    },
},

操作的思路:

  • 操作的prop字段为空,可以判断这个字段是否空,是空的话就是操作
  • 这个字段空的时候使用< slot >来填充操作下面的元素
  • 在table.vue触发父组件对应的事件函数

table.vue:添加下面红圈

<template>
    <tr class="tbody-content" v-for="(item, index) in bodyData" :key="index">
        <td
            class="info-box" 
            v-for="(colItem, colIndex) in headData" 
            v-if="colItem.prop"
            :class="[{ 'first-col clearfix': colIndex == 0 },colItem.class]">
                {{ item[colItem.prop] }}
        </td>

        <td class="operation" :key="colIndex" v-else @click.stop.capture="doThis($event, item, index)">
            <slot></slot>
        </td>
    </tr>
</template>

 触发父组件对应的操作事件函数,并把参数传过去

methods: {
    doThis(e, item, index) {
        // e.target.dataset.func是父组件操作下面元素的属性data-func
        this.$emit(e.target.dataset.func, item)
    },
},

userList.vue:添加两个元素和两个事件,data-func这个是来方便子组件table.vue触发对应的事件函数

<tableLocked 
    :headData="tableHead" 
    :bodyData="tableBody" 
    :isTableLeft='true'
    @goSort="sortClick"
    @goModify="modifyClick" 
    @goDelete="deleteClick">
        <span data-func="goModify">修改</span>
        <span data-func="goDelete">删除</span>
</tableLocked>
methods: {
    modifyClick (item) {
        console.log("修改:" + item)
    },
    deleteClick (item) {
        console.log("删除:" + item)
    },
},

完成代码:

table.vue

<template>
    <div>
        <div class="product-list">
            <!-- 可滑动的全表格 -->
            <div class="table-scroll-container" ref="tableScrollBox">
                <table class="table-scroll" border="0" cellpadding="0" cellspacing="0">
                    <tbody class="tbody">
                        <tr class="title-tr">
                            <th class="ta-c" v-for="(item,index) in headData" :key="index" :class="{ 'first-col': index == 0 }">
                                {{ item.name }}
                                <span class="sort" v-if="item.isSort" @click="onSort(item)">
                                    <i class="up" :class="{ active: item.SortType == 'Asc' }"></i>
                                    <i class="down" :class="{ active: item.SortType == 'Desc' }"></i>
                                </span>
