我已经实现了自定义列选择器对话框。当用户提交更改时，我有两个数组：
keysOfColumnsToShow (example: ['key1', 'key2', ...])
keysOfColumnsToHide (example: ['key3', 'key4', ...])
我已经调试了，密钥也很好。现在，我尝试在代码中应用更改。为此，我使用igGridHiding方法：
$(".grid").igGridHiding("showMultiColumns", keysOfColumnsToShow)
$(".grid").igGridHiding("hideMultiColumns", keysOfColumnsToHide)
问题是调用igGridHiding方法后，某些标头不在corrent列上方，而某些标头为空。
在不使用默认对话框的情况下管理隐藏/显示代码列的正确方法是什么？
答案 0 :(得分：2)
您能否提供有关您的方案的更多详细信息？我对此进行了调查，并准备了一个示例，但没有设法复制您正在描述的场景。
工作正常。您可以修改以下代码示例以进行演示吗？
