vue+elementUI 表头按钮

要实现下图，表头

 

 

方法1：

<el-table-column  label="操作" :render-header="renderHeaderCaseBody"></el-table-column>

 

             renderHeaderCaseBody(h, params) {
        let a =  [
                    h('el-button-group',[
                        // 文字提示
                        h('el-tooltip',{
                            props: {
                                disabled: false,
                                content: "批量编辑",
                                placement: "bottom",
                                effect: "light"
                            },
                        },
                        [
                            // 批量编辑
                            h('el-button', {
                                props: {
                                    size: "mini",
                                    type: "primary",
                                    icon: "el-icon-s-flag"
                                },
                                on: {
                                    click: () => {
                    this.isbodyTextAreaShow = true;
                    this.isBodyTabShowTable = false;
                    this.addCaseData.isbodyTextAreaButton = true;
                    this.resetValParamTextArea(this.bodyTableData, 2);
                                    }
                                }
                            }, "Bulk Edit")
                        ]),
                    ])
                ]
        return h('div', a);
      },

 

但是以上console控制台会有一个警告：使用scoped-slot比用render-header更简单

?

1	[Element Warn][TableColumn]Comparing to render-header, scoped-slot header is easier to use. We recommend users to use scoped-slot header.这

这个可以通过方法2解决。

 

方法2：

<el-table-column label="操作" scoped-slot>
  <template slot="header">
      <el-button-group>
          <el-tooltip :disabled="false" placement="bottom" effect="light">批量编辑</el-tooltip>
          <el-button size="mini" type="primary" icon="el-icon-s-flag" @click="BodyBulkEditClick">Bulk Edit</el-button>
      </el-button-group>
  </template>

  <template slot-scope="scope">
      <el-link type="info" :underline="false" icon="el-icon-close" @click.native="deleteRow(3, scope.$index, scope.row)" circle></el-link>
  </template>
</el-table-column>

这样就实现了，方法1的效果。
