＜el-table＞设置一列为固定字段，其他列为循环生成

  <el-table :data="tableData" style="width: 100%">
      <el-table-column
        prop="name"
        label="固定字段名"
        :formatter="formatter"
      >
      </el-table-column>
      <el-table-column
        v-for="(item, index) in wordsColumns"
        :prop="item.name"
        :label="item.label"
        :key="index"
      >
      </el-table-column>
    </el-table>
