Elment UI的el-table-column表头旁边有点击按钮类似的操作

   <el-table-column fixed="right" label="操作" ><!-- 表头 -->
{{--            <template slot="header" header="scope">--}}
{{--                <span>{{ "信息:" + subBureau }}&nbsp;&nbsp;</span>--}}
{{--                <span @click="selectBtn">选择</span>--}}
{{--            </template>--}}<template slot="header" header="scope"><span>{{ "操作" }}&nbsp;&nbsp;</span><span><el-button @click="addRowList()" type="warning" size="small">增加</el-button></span></template><template slot-scope="scope"><el-button @click="deleteRowList(scope.row,1)" type="warning" size="small">删除</el-button></template></el-table-column>

   deleteRowList(){console.log('del')},addRowList(){console.log('add')},

或

   <el-table-column label="操作" :render-header="renderHeader" width="150"><template scope="scope"><el-button type="warning" size="mini" icon="el-icon-edit" @click="handleEdit(scope.$index, scope.row)" circle></el-button><el-button type="danger" icon="el-icon-delete" size="mini" @click="handleDel(scope.$index, scope.row)" circle></el-button></template></el-table-column>

     // 表头操作栏按钮renderHeader(h, params) {let a =  [h('el-button-group',[// 文字提示h('el-tooltip',{props: {disabled: false,content: "增加测试用例",placement: "bottom",effect: "light"},},[// 增加按钮h('el-button', {props: {size: "mini",type: "primary",icon: "el-icon-add-location"},on: {click: () => {this.renderAddRow();}}})]),h('el-tooltip',{props: {disabled: false,content: "全局变量",placement: "bottom",effect: "light"                                }},[// 全局变量按钮h('el-button', {props: {size: "mini",type: "primary",icon: "el-icon-share"},on: {click: () => {this.renderAddRow();}}}),]),h('el-tooltip',{props: {disabled: false,content: "系统函数",placement: "bottom",effect: "light"                                }},[// 系统函数按钮h('el-button', {props: {size: "mini",type: "primary",icon: "el-icon-share"},on: {click: () => {this.renderAddRow();}}}),]),])]return h('div', a);},
