table表格的某一行数据如何回填

目的：table表格的某一行数据的输入框按钮触发对话框，对话框选择的数据再回填到table表格的这一行中。

1.插槽中传递本行的index: v-slot="{ row, $index }"

2.点击事件或者change事件传递index: @click="val => tpmClicked($index)"

记录这个index值：

const rowIndexTPM = ref<number>();
const tpmClicked = async index => {
rowIndexTPM.value = index;
dialogTPMVisible.value = true;
};
对话框选择后触发事件，使用这个index值：

const TPMchangeInfo = (jobNumber: string) => {
requireList.value[rowIndexTPM.value].JobNumber = jobNumber;
dialogTPMVisible.value = false;
changeInfo(requireList.value[rowIndexTPM.value]);
};

代码数据：

1. 记录index
    <el-table-column label="工号" prop="JobNumber">
      <template v-slot="{ row, $index }">
        <span v-if="editStatus">
          <el-input
            type="text"
            v-model="row.JobNumber"
            placeholder="请输入："
            @change="val => changeInfo(row)"
          >
            <template #suffix v-if="row.WorkerRole == 'TPM'">
              <el-button
                type="primary"
                @click="val => tpmClicked($index)"
                v-if="row.WorkerRole == 'TPM'"
                link
              >
                <el-icon>
                  <Connection />
                </el-icon>
              </el-button>
            </template>
          </el-input>
        </span>
        <span v-else>{{ row.JobNumber }}</span>
      </template>
    </el-table-column>



-->  触发的事件：
const rowIndexTPM = ref<number>();
const tpmClicked = async index => {
  rowIndexTPM.value = index;
  dialogTPMVisible.value = true;
};



2.对话框：
<el-dialog v-model="dialogTPMVisible" title="请选择TPM工号" width="20%">
    <el-tree-select
      v-model="Value"
      :data="TPMListInfo"
      filterable
      placeholder="请输入："
      @change="val => TPMchangeInfo(val)"
    />
  </el-dialog>

--> 事件触发：
const TPMchangeInfo = (jobNumber: string) => {
  requireList.value[rowIndexTPM.value].JobNumber = jobNumber;
  dialogTPMVisible.value = false;
  changeInfo(requireList.value[rowIndexTPM.value]);
};


--> 数据源：
const TPMListInfo = computed(() => {
  console.log("data houduan: ", props.TPMGroups);
  return props.TPMGroups.map(item => {
    return {
      value: "",
      label: item.DepName,
      children: item.TPMList.map(t => {
        return {
          value: t.JobNumber,
          label: t.WorkerName + "/" + t.JobNumber,
          children: []
        };
      })
    };
  });
});
