其他做法


首先,官网文档上是有可编辑单元格和可编辑行的。我研究了好几遍,也是半知半解,只会用

 官网做法

  • 有一定的局限性,单元格内只能是输入框(我试了一些别的,不太行)

代码直接照着文档粘贴,只说一下需要改动的地方

table的数据源,我们都是后端获取,所以这里把默认的清空就行。请求接口获取数据源,直接set进去就行

 然后记得给 Table 标签添加 rowKey 属性,绑定唯一值

 如果想单元格可编辑,记得添加   editable: true,

 下面是我自己练习的一个案例

import { Form, Input, Popconfirm, Table, Button } from 'antd'
import React, { useContext, useEffect, useRef, useState } from 'react'
import './Lll.css'
import axios from 'axios'

const EditableContext = React.createContext(null)
const EditableRow = ({ index, ...props }) => {
  const [form] = Form.useForm()
  return (
    <Form form={form} ***ponent={false}>
      <EditableContext.Provider value={form}>
        <tr {...props} />
      </EditableContext.Provider>
    </Form>
  )
}
const EditableCell = ({
  title,
  editable,
  children,
  dataIndex,
  record,
  handleSave,
  ...restProps
}) => {
  const [editing, setEditing] = useState(false)
  const inputRef = useRef(null)
  const form = useContext(EditableContext)
  useEffect(() => {
    if (editing) {
      inputRef.current.focus()
    }
  }, [editing])
  const toggleEdit = () => {
    setEditing(!editing)
    form.setFieldsValue({
      [dataIndex]: record[dataIndex],
    })
  }
  const save = async () => {
    try {
      const values = await form.validateFields()
      toggleEdit()
      handleSave({
        ...record,
        ...values,
      })
    } catch (errInfo) {
      console.log('Save failed:', errInfo)
    }
  }
  let childNode = children
  if (editable) {
    childNode = editing ? (
      <Form.Item
        style={{
          margin: 0,
        }}
        name={dataIndex}
        rules={[
          {
            required: true,
            message: `${title} is required.`,
          },
        ]}
      >
        <Input ref={inputRef} onPressEnter={save} onBlur={save} />
      </Form.Item>
    ) : (
      <div
        className="editable-cell-value-wrap"
        style={{
          paddingRight: 24,
        }}
        onClick={toggleEdit}
      >
        {children}
      </div>
    )
  }
  return <td {...restProps}>{childNode}</td>
}
const Lll = () => {
  const [dataSource, setDataSource] = useState([])
  const handleDelete = (key) => {
    const newData = dataSource.filter((item) => item.key !== key)
    setDataSource(newData)
  }
  const defaultColumns = [
    {
      title: '标题',
      dataIndex: 'title',
      width: '30%',
      editable: true,
      ellipsis: true,
    },
    {
      title: '分类',
      dataIndex: 'tab',
      editable: true,
      width: '20%',
    },
    {
      title: '浏览量',
      dataIndex: 'reply_count',
      editable: true,
      width: '20%',
    },
    {
      title: 'operation',
      dataIndex: 'operation',
      render: (_, record) =>
        dataSource.length >= 1 ? (
          <Popconfirm
            title="确定删除吗?"
            onConfirm={() => handleDelete(record.key)}
          >
            <a>删除</a>
          </Popconfirm>
        ) : null,
    },
  ]
  const handleSave = (row) => {
    const newData = [...dataSource]
    const index = newData.findIndex((item) => row.key === item.key)
    const item = newData[index]
    newData.splice(index, 1, {
      ...item,
      ...row,
    })
    setDataSource(newData)
  }
  const ***ponents = {
    body: {
      row: EditableRow,
      cell: EditableCell,
    },
  }
  const columns = defaultColumns.map((col) => {
    if (!col.editable) {
      return col
    }
    return {
      ...col,
      onCell: (record) => ({
        record,
        editable: col.editable,
        dataIndex: col.dataIndex,
        title: col.title,
        handleSave,
      }),
    }
  })

  // 点击收集
  const shouji = () => {
    console.log('收集到的值为', dataSource)
  }
  // 初始化操作
  useEffect(() => {
    axios
      .get('https://***odejs.org/api/v1/topics')
      .then((res) => {
        setDataSource(res.data.data)
      })
      .catch((err) => console.log(err))
  }, [])

  return (
    <div>
      <Table
        ***ponents={***ponents}
        rowClassName={() => 'editable-row'}
        bordered
        dataSource={dataSource}
        columns={columns}
        rowKey={(record) => record.id}
      />
      <Button onClick={shouji}>收集值</Button>
    </div>
  )
}
export default Lll

其他做法

  • 主要是用到了数据驱动视图的思想,只要数据变了,视图自然更新。需要什么标签,render里就写什么
  • render属性的值是个函数,默认有三个参数,第一个参数是当前行渲染的数据,第二个参数是后端返回给我们的完整的当前行数据,第三个参数是索引
  • 加的有校验,不想加校验就把Form相关的去掉就行
import React, { useState } from 'react'
import { Space, Table, Input, Button, DatePicker, Form } from 'antd'
import moment from 'moment'

export default function Mmm() {
  const [form] = Form.useForm()
  const columns = [
    {
      title: '标题',
      dataIndex: 'title',
      key: 'title',
      render: (_, record, index) => (
        <Form.Item
          name={'title' + record.id}
          rules={[
            {
              required: true,
              message: '不能为空!',
            },
          ]}
          initialValue={record.title}
        >
          <Input onBlur={(e) => upTitle(e, index)} />
        </Form.Item>
      ),
    },
    {
      title: '时间',
      dataIndex: 'time',
      key: 'time',
      render: (_, record, index) => (
        <Form.Item
          name={'time' + record.id}
          rules={[
            {
              required: true,
              message: '不能为空!',
            },
          ]}
          initialValue={moment(record.time, 'YYYY-MM-DD')}
        >
          <DatePicker onChange={(time) => upTime(time, index)} />
        </Form.Item>
      ),
    },
    {
      title: '操作',
      key: 'action',
      render: (_, record, index) => (
        <Space size="middle">
          <Button onClick={() => delItem(index)}>删除</Button>
        </Space>
      ),
    },
  ]
  const [data, setData] = useState([
    {
      id: 0,
      title: '标题1',
      time: '2023-03-13',
    },
    {
      id: 1,
      title: '标题2',
      time: '2023-03-14',
    },
  ])

  // 标题修改后失焦
  const upTitle = (e, index) => {
    let newArr = JSON.parse(JSON.stringify(data))
    newArr[index].title = e.target.value
    setData(newArr)
  }
  // 时间选择后
  const upTime = (time, index) => {
    let newArr = JSON.parse(JSON.stringify(data))
    newArr[index].time = time?.format('YYYY-MM-DD') || ''
    setData(newArr)
  }
  // 点击删除
  const delItem = (index) => {
    let newArr = JSON.parse(JSON.stringify(data))
    newArr.splice(index, 1)
    setData(newArr)
  }
  // 点击收集数据按钮
  const getData = () => {
    form.validateFields().then((res) => {
      // console.log(res)
      console.log('收集到的数据为', data)
    })
  }

  return (
    <div>
      <Form form={form}>
        <Table
          columns={columns}
          dataSource={data}
          rowKey={(record) => record.id}
        />
      </Form>
      <Button onClick={getData}>收集数据</Button>
    </div>
  )
}
