通过基础的Table表格来实现单元格内容的可编辑

 1.首先定位到需要编辑的列，替换el-table-column

           <el-table-column label="Editable Column" width="300">
              <template #default="{ row, column, $index }">
                <el-input
                  size="small"
                  v-if="
                   tableRowEditId === row.id &&
                   tableColumnEditIndex === column.id
                  "
                  v-model="row.taskId"
                  @blur="blurUnitInput(row, column)"
                  @keyup.enter="blurUnitInput(row, column)"
                />
                <span v-else class="hover-border">{{ row.taskId }}</span>
              </template>
            </el-table-column>

2.el-table 标签下面增加 cell-click 事件，当某个单元格被点击时会触发该事件

  <el-table :data="tableData" border style="width: 100%" @cell-click="showUnitInput">
    <el-table-column prop="date" label="Date" width="180" />
    <el-table-column prop="name" label="Name" width="180" />
     <el-table-column label="Editable Column" width="300">
              <template #default="{ row, column, $index }">
                <el-input
                  size="small"
                  v-if="
                   tableRowEditId === row.id &&
                   tableColumnEditIndex === column.id
                  "
                  v-model="row.taskId"
                  @blur="blurUnitInput(row, column)"
                  @keyup.enter="blurUnitInput(row, column)"
                />
                <span v-else class="hover-border">{{ row.taskId }}</span>
              </template>
            </el-table-column>
  </el-table>

3. 增加标识变量、事件方法，可以在 blurUnitInput 方法里面实现修改的接口

const tableRowEditId = ref()
const tableColumnEditIndex = ref()
const showUnitInput = (row: any, column: any) => {
  // console.log('row', row)
  // console.log('column', column)
  //赋值给定义的变量
  tableRowEditId.value = row.id //确定点击的单元格在哪行 如果数据中有ID可以用ID判断，没有可以使用其他值判断，只要能确定是哪一行即可
  tableColumnEditIndex.value = column.id //确定点击的单元格在哪列
}
const blurUnitInput = (row: { [x: string]: boolean }, column: any) => {
  tableRowEditId.value = null
  tableColumnEditIndex.value = null
  //在此处调接口传数据
  console.log(row)
  console.log(column)
}

4.增加一个样式，使可编辑的单元格鼠标悬停时显示虚线边框

.hover-border {
  border: none; /* 默认无边框 */

}

.hover-border:hover {
  border: 1px dotted #165DFF; /* 鼠标悬停时显示虚线边框 */
  padding: 2px;
}
