用vue+element ui开发管理系统时，使用el-table做表格，当表格列过多的时候，想要做成可选表头的，实现表格列的筛选显示，效果如下：
代码文件结构：
废话不多说，直接上代码：
第一步：新建名为 TableHeaderRender.vue 的文件

第三步：在页面中引入operateTable并使用
<template>
<div class=”tableView”>
<div class=”content”>
<operateTable
v-loading=”loading”
:dataSource=”operateTableData”
:columns=”operateTableColumns”
:options=”operateTableOption”
:defaultColumn=”defaultColumns”
:totalColumn=”totalColumns”
:defaultSelectedColumn=”defaultSelectedColumn”
@sort-change=”sortChange”
@saveSettingColumns=”saveSettingColumns”
></operateTable>
</div>
</div>
</template>
<script>

],
operateTableColumns: [
{

},
},
{

minwidth: 150,
sortable: “custom”,

],
operateTableOption: {

columnsSelect: true,
maxHeight: 300,
},
defaultColumns: [“操作”, “日期”, “姓名”, “地址”],
totalColumns: [“操作”, “日期”, “姓名”, “地址”],
//所有用户默认勾选的列 用于初始化
defaultSelectedColumn: [],
};
},
methods: {
//表头排序
sortChange(column, prop, order) {
if (column.order === “ascending”) {
this.orderfield = column.prop;
this.orderby = “ASC”;
} else if (column.order === “descending”) {
this.orderfield = column.prop;
this.orderby = “DESC”;
} else {
this.orderfield = “”;
this.orderby = “”;
}
// this.getTabldHandle();
},
//保存自定义字段
saveSettingColumns(data) {
console.log(data);
},
},
mounted() {},
};
</script>
<style>
.tableView {
width: 100%;

}
.content {
padding: 60px;
