我不是 100% 确定我应该如何表达这个问题，但我会尽力而为。
我有一个 PointCtrlForm，它在 TableLayoutPanel 中有一个 DataGridView。DataGridView 作为 Fill 停靠在表格中。PointCtrlForm 停靠到另一个设置为 MDIParent 的窗口，停靠样式属性设置为 Fill。
调整主窗口的大小可以正确调整 PointCtrlForm 的大小，然后它也应该调整 DataGridView 的大小。好吧，至少“一半”的调整大小可以正常工作。扩大主窗口也会扩大 datagridview，这是我所期望的，但如果我将主窗口缩小到某个点，DataGridView 会停止缩小并隐藏列而不显示滚动条。
我检查了所有列都没有启用 Frozen 属性，检查了 datagridview 和子窗口是否正确停靠，并检查了滚动条属性设置为两者。
编辑： AutoSizeColumnsMode 也是填充。
我将在此处发布 Designer.cs 的内容。我会很感激任何指导。
