C＃WinForm：表格布局 - 无法添加其他元素

Question

我遇到了一些WinForms的奇怪问题。 我的表格是这样构建的：

我需要在右上角添加一些其他元素（固定到面板的几个进度条） 但设计师不会让我放置它们（光标转到“停在这里”） 我也不能通过代码添加额外的面板。

以下是TL的属性

  this.tableLayoutPanelMain.ColumnCount = 2;
  this.tableLayoutPanelMain.ColumnStyles.Add(new System.Windows.Forms.ColumnStyle(System.Windows.Forms.SizeType.Absolute, 466F));
