一.table组件的方法，事件
二.常用的事件，属性
(一).属性
1.多选框（type = "selection"） 需要实现勾选的功能
在<el-table> 内加入<el-table-column type="selection" width="55"></el-table-column>
2. :data="tableData" 是table的数据绑定
<el-table :data="tableData">
export default {
data() {
return{
tableData: [],
}
}
}
3.formatter 用来格式化内容
对table的值进行处理。Function(row, column, cellValue, index){}
A.使用formatter需要注意以下几点：
①无论formatter出何种形式，格式化出的DOM一定都是被包含在默认的div标签内
②在写formatter函数时要保证有值返回，否则单元格没有内容可展示，所以if的时候别忘了else
③formatter函数不会作用在列属性checkbox为true的单元格上，checkbox列是组件预留的。
<template>
<el-table :data="tableData3" ref="multipleTable">
<el-table-column type="selection" width="55" ></el-table-column>
<el-table-column type="index" label="序号" width="60"></el-table-column>
<el-table-column prop="sex" label="性别" width="100" :formatter="formatSex"></el-table-column>
<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="IsAudit" :formatter="formatterColumn" label="审核状态" ></el-table-column>
<el-table-column prop="address" label="地址"></el-table-column>
</el-table>
</template>
<script>
export default {
data() {
return {
tableData3: [{
id:'1',
date: '2016-05-03',
name: '王小虎',
address: '上海市普陀区金沙江路 1518 弄',
IsAudit:0,
sex:'1'
}, {
id:'2',
date: '2016-05-02',
name: '王小虎',
address: '上海市普陀区金沙江路 1518 弄',
IsAudit:1,
sex:'0'
}, {
id:'3',
date: '2016-05-02',
name: '王小虎',
address: '上海市普陀区金沙江路 1518 弄',
IsAudit:10,
sex:'-1'
}]
}
},
mounted() {
},
methods: {
formatSex: function (row, column, cellValue, index) {
return row.sex == 1 ? '男' : row.sex == 0 ? '女' : '未知';
},
//状态改成汉字
formatterColumn(row, column) {
switch(row.IsAudit){
case 0:
return '未通过';
break;
case 1:
return '审核通过';
break;
case 10:
return '待审核';
break;
case 9:
return '草稿';
break;
default:
return '未知';
}
}
}
}
</script>

4.selectable (row, index) 是否可以选中
注意：仅对 type=selection 的列有效，类型为 Function，Function 的返回值用来决定这一行的 CheckBox 是否可以勾选
使用：
<template>
<el-table :data="tableData3" ref="multipleTable" @row-click="handleCurrentChange">
<el-table-column type="selection" width="55" :selectable="selectable"></el-table-column>
</el-table>
</template>
<script>
export default {
methods: {
selectable(row, index){
if(index === 1){
return true;
}else{
return false;
}
}
}
}
</script>
只有第二条是可以选中 其他不能
image.png
(二).方法
1.row-click 点击行事件
<el-table @row-click="handleRowChange">
handleRowChange(row, event, column){ row此行的数据 }
2.selection-change 获取选中的所有值
<el-table @selection-change="selectionRowsChange">
selectionRowsChange(val){ val 选中的值}
image.png
1.table tr 点击 复选框选中 再次点击 复选框取消选中
①设置一个全局函数
exports.install = function (Vue, options) {
//删除数组 指定的元素
Vue.prototype.removeByValue=function(arr, val){
for(var i=0; i<arr.length; i++) {
if(arr[i] == val) {
arr.splice(i, 1);
break;
}
}
};
};

3.table行内编辑
vue slot的scope传递，要表述的意思组件中slot这个插槽上可以赋值各种属性，在调用组件的页面中可以使用<template slot-scope="props"> 来获取插槽上的属性值，获取到的值是一个对象。
(1).一行一行编辑
<template>
