通過在vue中使用element的table表格，實現數據動態渲染，并且動態渲染表頭。通過在父組件中引入子組件表格，然后向子組件傳遞表格數據和表頭數據。

子組件table中template模板

<el-table   :data="this.tableData"  height="400px"   max-height="400px"   size="small"  row-class-name="row"  cell-class-name="column"  :row-  :cell-  :highlight-current-row="true"  @cell-click="cellClick"  fit  >  <el-table-column    v-for="(item, index) in tableLabel"    :key="index"     :prop="item.prop"     :width="item.width"     :label="item.label">  </el-table-column></el-table>

接收父組件傳過來的數據

props: { tableData: { // 父組件傳遞過來的表格數據    type: Array,    default: []  },  tableLabel: { // 父組件傳遞過來的表頭數據    type: Array,    default: () => {      return []    }  }}

父組件

<file-table  :tableData="tableData" :tableLabel="tableLabel"></file-table>data() { return { // 子組件的表格數據 tableData: [  {id: 1, date: '2018-07-24', sales: 23.34, sale: 137597.76, const: 102203.71, profit: 35394.05},  {id: 2, date: '2018-07-24', sales: 23.34, sale: 137597.76, const: 102203.71, profit: 35394.05},  {id: 3, date: '2018-07-24', sales: 23.34, sale: 137597.76, const: 102203.71, profit: 35394.05},  {id: 4, date: '2018-07-24', sales: 23.34, sale: 137597.76, const: 102203.71, profit: 35394.05},  {id: 5, date: '2018-07-24', sales: 23.34, sale: 137597.76, const: 102203.71, profit: 35394.05},  {id: 6, date: '2018-07-24', sales: 23.34, sale: 137597.76, const: 102203.71, profit: 35394.05},  {id: 7, date: '2018-07-24', sales: 23.34, sale: 137597.76, const: 102203.71, profit: 35394.05},  {id: 8, date: '2018-07-24', sales: 23.34, sale: 137597.76, const: 102203.71, profit: 35394.05},  {id: 9, date: '2018-07-24', sales: 23.34, sale: 137597.76, const: 102203.71, profit: 35394.05},  {id: 10, date: '2018-07-24', sales: 23.34, sale: 137597.76, const: 102203.71, profit: 35394.05},  {id: 11, date: '2018-07-24', sales: 23.34, sale: 137597.76, const: 102203.71, profit: 35394.05},  {id: 12, date: '2018-07-24', sales: 23.34, sale: 137597.76, const: 102203.71, profit: 35394.05} ], // 子組件的表頭數據 tableLabel: [      {label: '', width: '40', prop: 'id'},      {label: '日期', width: '', prop: 'date'},      {label: '銷售量', width: '', prop: 'sales'},      {label: '銷售額', width: '', prop: 'sale'},      {label: '成本', width: '', prop: 'const'},      {label: '利潤', width: '', prop: 'profit'}    ] }}

問題：這種方式只能在一個組件中動態渲染，但是當我們需要操作每一列數據的時候，沒法操作，因為element table再帶的方法是每個單元格點擊事件，而不符合我們需求，如何能實現表格動態渲染，并且每個組件都能使用，還能夠實現操作的可控的列，下節分享。
