简单 table 封装
面对 element-ui table 有好多可以复用，首先来学习下简单封装复用 table 写法，实现高效小前端，减少一下代码复用，提高效率完成 table 数据渲染复用
1、首先创建一个 table 封装的组件
<template>
<!--
@param tableData 父组件传值
@param loading [Boolean] 加载提示
@param border [Boolean] table 边框
-->
<el-table
ref="table"
:data="tableData"
v-loading="loading"
element-loading-text="Loading"
:border="border"
fit highlight-current-row
tooltip-effect="dark"
style="width:100%"
@sort-change="handleSortChange"
@selection-change="handleSelectionChange">
<!--
@name 展开查看详情
@param tableLabel 父组件传值
@param label [string] 名称
@param render 配置格式化数据
-->
<el-table-column type="expand">
<template slot-scope="scope">
<el-form
class="table-expand"
>
<el-form-item
v-for="(item,index) in tableLabel"
:key="index"
:label="item.label">
<span v-if="item.render">
{{item.render(scope.row)}}
</span>
<span v-else>{{scope.row[item.param]}}</span>
</el-form-item>
</el-form>
</template>
</el-table-column>
<!--
@name 操作
@param tableOption 父组件传值
@param label [string] 名称
@param width [string] 宽度
@param options [array] 按钮数组
@param type 按钮类型
@param icon 按钮图标
@param handleButton 按钮方法
-->
<el-table-column
v-if="tableOption.label"
:width="tableOption.width"
:label="tableOption.label"
align="center"
class-name="small-padding fixed-width">
<template slot-scope="scope">
<el-button
v-for="(item,index) in tableOption.options"
:key="index"
:type="item.type"
:icon="item.icon"
@click="handleButton(item.methods,scope.row,scope.$index)"
size="mini">
{{item.label}}
</el-button>
</template>
</el-table-column>
<!--
@name 标题 + 表格数据显示
@param tableLabel 父组件传值
@param width【string】宽度
@param align【string】对齐方式
@param label [string] 名称
@param sortable [Boolean] 排序
@param render 配置格式化数据
-->
<div
v-for="(item,index) in tableLabel"
:key="index">
<el-table-column
v-if="item.show"
:width="item.width ? item.width :''"
:align="item.align"
:label="item.label"
:prop="item.param"
:sortable="item.sortable ?'custom': false">
<template slot-scope="scope">
<span v-if="item.render">
{{item.render(scope.row)}}
</span>
<span v-else>{{scope.row[item.param]}}</span>
</template>
</el-table-column>
</div>
</el-table>
</template>
<script>
/**
* @name 表格封装
* @export TableElement
* @param loading [Boolean] 配置加载提示
* @param tableData [Array] 数据
* @param tableMain [Array] 数据详情
* @param tableLabel [Array] 配置表格头部
* @param tableOption [Object] 操作按钮
* @param border [Boolean] 配置边框
*/
export default {
props:{
loading:{
type:Boolean,
default:false
},
tableData:{
type:Array,
default: () => {return []
}
},
tableMain:{
type:Array,
default: () => {return []
}
},
tableLabel:{
type:Array,
default: () => {return []
}
},
tableOption:{
type:Object,
default: () => {return {}
}
},
border:{
type:Boolean,
default: false
}
},
components:{},
methods: {
// methods: 按钮名称 row：同一行的数据 index：第几行（0 开始）handleButton(methods,row,index){ // 按钮事件
console.log(row)
this.$emit('handleButton',{'methods':methods,'row':row})
},
handleSortChange(val){ // 排序
this.$emit('handleSortChange',val)
},
handleSelectionChange(val){this.$emit('handleSelectionChange',val)
}
}
}
</script>
<style lang="scss" scoped>
.table-expand {
font-size: 0;
display: flex;
flex-wrap: wrap;
}
.table-expand label {
width: 90px;
color: #99a9bf;
}
.table-expand .el-form-item {
margin-right: 0;
margin-bottom: 0;
width: 50%;
}
</style>2、table 组件导入使用
<template>
<div>
<TableElement
:loading="loading"
:table-data="tableData"
:table-label="tableLabel"
:table-option="tableOption"
@handleButton="handleButton"
@handleSortChange="handleSortChange"
@handleSelectionChange="handleSelectionChange"
></TableElement>
</div>
</template>
<script>
import TableElement from "@/components/Table/index"; // 导入 table 组件，具体路径以自己为主
export default {data() {
return {
loading:false,
border:true,
tableData: [
{
usr:'yy',
company:'hahahha',
email:'find@allyum.com',
registTime:'2019 8',
status:'1'
},
{
usr:'aa',
company:'hahahha',
email:'find@allyum.com',
registTime:'2019 8',
status:'1'
},{
usr:'c',
company:'hahahha',
email:'find@allyum.com',
registTime:'2019 8',
status:'1'
},{
usr:'b',
company:'hahahha',
email:'find@allyum.com',
registTime:'2019 8',
status:'1'
}
],
tableLabel: [{ label: "用户名", param: "usr", align: "center", sortable: true,show:true},
{label: "公司名称", param: "company", align: "center",show:false},
{label: "办公邮箱", param: "email", align: "center", width: "200",show:true},
{label: "注册时间",param: "registTime",lign: "center",show:true,ortable: true},
{ label: "审核状态",param: "status",align: "center",show:true,sortable: true,
render: row => {if (row.status === 0) {return "未审核";} else if (row.status === 1) {return "审核通过";} else if (row.status === 2) {return "审核不通过";} else {return "禁用";}
}
}
],
tableOption: {
label: "操作",
width: "200",
options: [
{
label: "预览",
type: "primary",
icon: "el-icon-view",
methods: "preview"
},
{
label: "审核",
type: "primary",
icon: "el-icon-upload2",
methods: "audit"
}
]
}
};
},
methods:{handleButton(methods,row,index) {switch(methods) {
case 'preview':
this.preview()
case 'audit':
console.log('audit')
}
},
preview() {console.log('preview');
},
// 排序规则
handleSortChange() {console.log('排序规则')
},
handleSelectionChange() {}
},
components: {TableElement}
};
</script>
<style lang="scss" scoped>
</style>
总结
- 简单的学习封装，如果有更好建议可以在下面留言
- 上面的有写规则例如排序的还没完善，后面更新一些规则进去
