【已解决】Reactjs的Antd Pro中实现表格中支持可编辑的单元格

折腾:
【未解决】Antd Pro的ReactJS中实现既可以编辑单元格值又可以拖动排序的表格
期间,需要先去合并进来,使得Reactjs的Antd Pro中的Table中的cell是可以编辑值的。
经过一番折腾,参考:
https://ant.design/components/table-cn/#components-table-demo-edit-cell
中的示例代码。
【总结】
最后用代码:
src/components/EditableCell/index.js
import React, { PureComponent } from 'react';
import styles from './index.less';
import { Form, Input } from 'antd';

const FormItem = Form.Item;
const EditableContext = React.createContext();

const EditableRow = ({ form, index, ...props }) => (
  <EditableContext.Provider value={form}>
    <tr {...props} />
  </EditableContext.Provider>
);

export const EditableFormRow = Form.create()(EditableRow);

// export default class EditableCell extends PureComponent {
export class EditableCell extends PureComponent {

  state = {
    editing: false,
  }

  componentDidMount() {
    console.log("EditableCell componentDidMount: this.props.editable", this.props.editable)

    if (this.props.editable) {
      document.addEventListener('click', this.handleClickOutside, true);
    }
  }

  componentWillUnmount() {
    if (this.props.editable) {
      document.removeEventListener('click', this.handleClickOutside, true);
    }
  }

  toggleEdit = () => {
    console.log("toggleEdit=")
    console.log("this.state.editing=", this.state.editing)

    const editing = !this.state.editing;
    this.setState({ editing }, () => {
      if (editing) {
        this.input.focus();
      }
    });
  }

  handleClickOutside = (e) => {
    const { editing } = this.state;
    if (editing && this.cell !== e.target && !this.cell.contains(e.target)) {
      this.save();
    }
  }

  save = () => {
    console.log("save")
    const { record, handleSave } = this.props;
    console.log("record=", record)
    this.form.validateFields((error, values) => {
      console.log("form.validateFields=: error", error, ", values=", values)

      if (error) {
        return
      }
      this.toggleEdit();
      handleSave({ ...record, ...values });
    });
  }

  render() {
    const { editing } = this.state;

    const {
      editable,
      dataIndex,
      title,
      record,
      index,
      // handleSave,
      ...restProps
    } = this.props;

    console.log("editing=", editing, ", editable=", editable, ", record=", record)

    return (
      <td ref={node => (this.cell = node)} {...restProps}>
        {editable ? (
          <EditableContext.Consumer>
            {(form) => {
              console.log("EditableContext.Consumer: form=", form)

              this.form = form;
              return (
                editing ? (
                  <FormItem style={{ margin: 0 }}>
                    {form.getFieldDecorator(dataIndex, {
                      rules: [{
                        required: true,
                        message: `${title} is required.`,
                      }],
                      initialValue: record[dataIndex],
                    })(
                      <Input
                        ref={node => (this.input = node)}
                        onPressEnter={this.save}
                      />
                    )}
                  </FormItem>
                ) : (
                  <div
                    className={styles.editableCellValueWrap}
                    // className={styles.nonEditableCellValueWrap}
                    style={{ paddingRight: 5 }}
                    onClick={this.toggleEdit}
                  >
                    {restProps.children}
                  </div>
                )
              );
            }}
          </EditableContext.Consumer>
        ) : restProps.children}
      </td>
    );
  }
}
src/components/EditableCell/index.less
@import '~antd/lib/style/themes/default.less';

.editable-cell {
  position: relative;
}

// .nonEditableCellValueWrap {
//   padding: 5px 12px;
//   cursor: pointer;
//   background: grey;
// }

.editableCellValueWrap {
  padding: 5px 12px;
  // padding: 2px 4px;
  cursor: pointer;
}

// .editable-row:hover .editableCellValueWrap {
// .editableRow:hover .editableCellValueWrap {
.editableCellValueWrap:hover {
  border: 1px solid #d9d9d9;
  border-radius: 4px;
  padding: 4px 11px;
  // padding: 2px 4px;
}

                form={this.props.form}
              />
....
      </PageHeaderLayout>
    );
  }
}
实现要的效果:
鼠标移动上去有边框提示可以编辑:
对于不可编辑的,没边框:
点击可以编辑的cell时,显示输入框:
可以一直输入,内容多了后,编辑时 一直往后输入,输入完成后,回车 或者点击其他区域,即可保存:
内容超过宽度时可以自动换行显示
