在el-table中点击单元格时使用el-input或其他表单组件编辑单条数据。会出现聚焦不上的问题，需要手动点击才能够聚焦。究其原因是因为点击单元格时页面已自动聚焦到单元格，此时无法自动聚焦到对应的表单，需要手动设置。

<template>
  <el-table
    :data="tableData"
    @cell-click="cellclickHandle"
  >
	<el-table-column prop="text" label="编辑" align="right">
      <template #default="{ row }">
        <el-input
          v-focus
          style="height: 20px"
          v-model="row.text"
          @blur="cellBlur(1, row)"
          v-if="row?.isEdit ?? false"
        />
        <span v-else>{{ row.text }}</span>
      </template>
    </el-table-column>
  </el-table>
</template>

<script setup>
import { reactive } from "vue"
  
....

//自定义指令
const vFocus = {
  mounted: el => {
    //清除el-table的cell聚焦
    document.activeElement.blur()
    const targetInput = el.getElementsByTagName("input")[0]
    targetInput.focus()
  }
}

//表格点击
let cacheRow = reactive({})
const cellclickHandle = (row, column) => {
  const { property } = column
  if (!["text"].includes(property)) return
  cacheRow = JSON.parse(JSON.stringify(row))
  if (property === "text") {
    row.isEdit = true
  } 
}

const cellBlur = async (input, row) => {
  row.isEdit = false
  if (cacheRow.text == row.text) return
  await ...
  ElMessage.success("编辑成功")
}
</script>
