table下td选项相同报错,渲染出来的还是前面一个table的td(_self.$scopedSlots.default is not a function)

_self.$scopedSlots.default is not a function //报错提示

<el-table :data="tableData5" border key="tableData5">
  <el-table-column
    prop="drivingNum" label="编号"
    header-align="center" align="center">
  </el-table-column>

<el-table>

//table上加个key即可不复用td从而重新渲染td数据
