Tkinter – Spaltengruppierung in Treeview ⇐ Python

[Anonymous]

Ich habe eine Tabelle, die aus mehreren Label-Widgets erstellt und mit der Methode „grid()“ angelegt wurde. Ich kann mehrere Spalten in der Kopfzeile mithilfe von rowspan und Columnspan gruppieren, um die Informationen auf eine bestimmte Art und Weise zu organisieren.
Das meiste davon kann ich problemlos mit einem Treeview-Widget replizieren, aber ich weiß nicht, wie ich die Kopfzeile auf die gleiche Weise wie zuvor organisieren soll. Ist das möglich?
Dieses Bild zeigt beide Tabellen. In Blau die Kopfzeile, die ich in der zweiten Tabelle replizieren möchte.


Code, der beide Tabellen anzeigt:

Code: Select all

self.style.configure('Header.TLabel', borderwidth=1, background='#9EBDF0', relief=tk.GROOVE)

self.lbf = ttk.Labelframe(parent, text='Table with Label')
self.lbf.grid(row=0, column=0, sticky='NSWE')

self.lbf.rowconfigure(list(range(10)), weight=0)
self.lbf.columnconfigure(list(range(10)), weight=1)

Ich verwende Python 3.13.7, obwohl das wahrscheinlich nicht relevant ist.
