官网代码（在取消选中状态的时候不生效）

  rowSelection() {
      return {
        onChange: (selectedRowKeys, selectedRows) => {
          console.log(`selectedRowKeys: ${selectedRowKeys}`, 'selectedRows: ', selectedRows);
        },
        getCheckboxProps: record => ({
          props: {
            disabled: record.name === 'Disabled User', // Column configuration not to be checked
            name: record.name,
          },
        }),
      };
    },

修改后台的代码

    rowSelection() {
      const { selectedRowKeys } = this  //必须加
      return {
        selectedRowKeys,  //必须加
        onChange: (selectedRowKeys, selectedRows) => {
          this.selectedRowKeys = selectedRowKeys
          this.selectedRows = selectedRows
        },
        getCheckboxProps: (record) => ({
          props: {
            disabled: record.status !== 3, // Column configuration not to be checked
            status: record.status,
          },
        }),
      }
    },
