【问题描述】：
显示/隐藏 Dojo 数据网格的最佳方式是什么？
我正在编写一个页面，该页面在显示数据网格之前需要一些用户输入。因此，理想情况下，页面的网格部分在页面加载时应该是空白/空的。一旦用户提供了特定的输入，网格就会出现在指定的位置。
我尝试设置 style="display:none" 然后编写 js 来设置 display="block" 并在 none 和 block 之间切换，但它只显示网格的轮廓。
如果我省略 style="display:none" 网格在加载时显示，我可以随后隐藏/取消隐藏它而不会出现任何问题。
我很困惑为什么当我在加载时设置 display=none 时它的行为会有所不同。解决此问题的方法或替代方法是什么？
非常感谢任何见解。
