前言

antd 的table表格拖拽列，会导致触发排序问题，解决方案如下，相当于加一个点击的事件判断，如果是拖拽，则不触发。

解决代码如下：

import { Resizable } from 'react-resizable'


class ResizeableTitle extends React.Component {
  render() {
    const { onResize, width, onClick, ...restProps } = this.props;
    return (
      <Resizable
        width={width}
        height={0}
        onResizeStart={() => (this.resizing = true)}
        onResizeStop={() => {
          setTimeout(() => {
            this.resizing = false;
          });
        }}
        onResize={onResize}
      >
        <th
          onClick={(...args) => {
            if (!this.resizing && onClick) {
              onClick(...args);
            }
          }}
          {...restProps}
        />
      </Resizable>
    );
  }
}

在拖拽表格中使用

components = {
    header: {
      cell: ResizeableTitle
    }
  }
