This article mainly introduces VUE element-ui to write a sample code for reusing the Table component. It has certain reference value. Interested friends can refer to it. I hope it can help everyone.
The table component of Ele.me is very powerful and is basically sufficient for various tables in the project, but...I am not used to its column-based operations =. =So it was changed to another way (I won’t tell you that the essence has not changed).
There are many tables in the project, so reusability is the most important
Step 1
Let’s start with a basic table Display the tableData of
official example
tableData: [{ date: '2016-05-02', name: '王小虎', address: '上海市普陀区金沙江路 1518 弄' }, { date: '2016-05-04', name: '王小虎', address: '上海市普陀区金沙江路 1517 弄' }, { date: '2016-05-01', name: '王小虎', address: '上海市普陀区金沙江路 1519 弄' }, { date: '2016-05-03', name: '王小虎', address: '上海市普陀区金沙江路 1516 弄' }]
table.vue
<template> <el-table :data="tableData" border> <el-table-column prop="date" label="日期"></el-table-column> <el-table-column prop="name" label="姓名"></el-table-column> <el-table-column prop="address" label="地址"></el-table-column> </el-table> </template>
Step 2
Simplify the table:
//table.vue <template> <el-table :data="tableData" border> <el-table-column v-for="(item,key) in tableKey" :key="key" :prop="item.value" :label="item.name"></el-table-column> </el-table> </template> <script> export default{ name: 'table', data(){ return{ tableData:[...], tableKey: [{ name: 'date', value: '日期' },{ name: '姓名', value: 'name' },{ name: '地址', value: 'address' }] } } } </script>
Step 3
To reuse table.vue is to give it the data and tell it my field name at the same time
Create a new parent component sl_table.vue
//sl_table.vue <template> <sl-table :tableData="tableData" :tableKey="tableKey"></sl-table> </template> <script> import Table from '@/components/table' export default{ name: 'sl-table', data(){ return { tableData: [...] tableKey: [{ name: 'date', value: '日期' },{ name: '姓名', value: 'name' },{ name: '地址', value: 'address' }] } }, components: { 'sl-table': Table } } </script>
table.vue is even simpler
//table.vue <template> <el-table :data="tableData" border> <el-table-column v-for="(item,key) in tableKey" :key="key" :prop="item.value" :label="item.name"></el-table-column> </el-table> </template> <script> export default{ name: 'table', data(){ return{ } }, props:['tableData','tableKey'], } </script>
Step 4
can be modified according to needs The form of table
Column width
This is relatively simple, you can directly add an attribute
//sl_table.vue ... data(){ return { tableData: [...] tableKey: [{ name: 'date', value: '日期', width: 80 },{ name: '姓名', value: 'name', width: 80 },{ name: '地址', value: 'address' }] } }, ...
table.vue
//table.vue ... <el-table-column v-for="(item,key) in tableKey" :key="key" :prop="item.value" :label="item.name" :width="item.width"></el-table-column> ...
Customize the template column
If we need to tell the component which is a custom column, so add a property operate
table.vue
<el-table-column v-for="(item,key) in tableKey" v-if="!item.operate" :key="key" :prop="item.value" :label="item.name" :width="item.width"></el-table-column> <!-- 自定义 --> <el-table-column v-else> <template scope="scope"> <slot :name="item.value" :$index="scope.$index" :row="scope.row"></slot> </template> </el-table-column> //sl_table.vue <sl-table :tableData="tableData" :tableKey="tableKey"> <template slot="date" scope="scope"> <span>{{ scope.row.date | DateFilter }}</span> </template> </sl-table> ... data(){ return { tableData: [...] tableKey: [{ name: 'date', value: '日期', operate: true },{ name: '姓名', value: 'name', operate: false },{ name: '地址', value: 'address', operate: false }] } }, filters: { DateFilter(){...} } ...
Table expand row
Similar to width, as long as sl_table.vue passes in an isExpand attribute. Here is an effect that can only expand one row at a time:
//sl_table.vue <sl-table :tableData="tableData" :tableKey="tableKey" :isExpand="true" :isExpandOnly="true"> <template slot="expand" scope="scope"> {{...expand something}} </template> ... </sl-table>
table.vue
//table.vue <el-table :data="tableData" border @expand="handleExpand" ref="raw_table"> <el-table-column v-if="isExpand" type="expand"> <template scope="scope"> <slot name="expand" :$index="scope.$index" :row="scope.row"></slot> </template> </el-table-column> </el-table> ... props: ['tableData','tableKey','isExpand','isExpandOnly'], methods: { handleExpand(row,is_expand){ if(this.isExpand && this.isExpandOnly){ this.$refs.raw_table.store.states.expandRows = expanded ? [row] : [] } } }
Other (sorting, multi-select) operations are also added similarly. . . No need to go into details.
