方法

    handleCheckboxChange(row, selectedField) {
  //先取消其他checkbox的选择
      for (const field in row) {
        if (row.hasOwnProperty(field) && field !== selectedField && field.startsWith('column1Selected')) {
          row[field] = false;
        }
      }
    },

• row.hasOwnProperty(field)：确保 field 是 row 对象自身的属性，而不是继承自原型链的属性。
• field !== selectedField：确保当前属性不是被选中的那个checkbox对应的属性。这是为了避免将当前选中的checkbox状态设置为 false。
• field.startsWith('column1Selected')：确保属性 名以 'column1Selected' 开头。这是为了过滤出与checkbox相关的属性。
• row[field] = false;：如果上述条件都满足，就将当前属性的值设置为 false，即取消选择对应的checkbox。
