canvas 上的树视图框架
Treeview frame on canvas
这段代码有两个问题：
1.我无法让树视图框架填满整个canvas（垂直）
2.不想显示第一列
我该如何解决这些问题？

I can't get the treeview frame to fill the entire canvas (vertically)
树没有填满 canvas 的问题是因为它在一个框架中，而框架没有填满 canvas。看起来你正试图在你的 OnCanvasConfigure 方法中解决这个问题，但是有很多错误阻止它工作。
首先，你有一个迭代 self.sensorsStatsFrame.grid_slaves() 的循环，但是你没有定义 self 并且没有名为 sensorsStatsFrame 的小部件，所以这个函数在它得到之前会失败有机会改变框架的高度。因为这段代码会抛出错误，所以函数中的后续代码不会 运行.
接下来，您尝试调用 self.canvas.configure，但同样没有 self 和 self.canvas，因此该语句将失败。您还使用 self.canvas_frame，但同样，它不存在，因此代码将失败。
如果您解决了所有这些问题，代码应该允许将框架配置为与 canvas 相同的宽度和高度，从而解决您提出的第一个问题。
I don't want the first column to be displayed
treeview 属性 show 允许您定义要显示树的哪些部分。您为其分配一个包含 "tree" and/or "headings" 的列表。您不想看到第一列，它由 "tree" 表示。因此，要隐藏该值，您希望将 "headings" 作为列表中用于 show 属性的唯一值传递。
tree["show"] = ["headings"]
