javascript - element ui

Question

<el-table :data="tableData">
  <el-table-column prop="name"></el-table-column>
</el-table>

tableData [{
  name: 'irene'
}]

nameVariable is a variable, value is equal to 'name', when I change the column to <el-table-column :prop="nameVariable"></el-table-column>, the data is not displayed Yes, why is this?

Answer 1

The principle of this component is like this
: data is equivalent to a variable
prop is equivalent to the key of the variable
prop must be: the key of the data variable
So your problem should be a calling problem, prop cannot call other variables

Answer 2

For this question, please take a look at the demo on the official website
<el-table :data="tableData" style="width: 100%">

<el-table-column prop="date" label="日期" width="180"></el-table-column>

</el-table>
export default {

    data() {
        return {
            tableData: [{
                date: '2016-05-02',
                }]
                }
            }
          }
官网demo提示，prop后面跟的数据是colum中的key值，而且没有使用v-bind:prop。
你可以把列改为<el-table-column prop="nameVariable"></el-table-column>
然后对应的data数据中，将列的key值也改成nameVariable。那么数据就可以显示了

If you changed it at the top, you should change it at the bottom too
