Moin. Ich brauche wieder mal Hilfe von den JTable-Cracks.
Ich hab mir aus dem Netz ein schönes Beispiel für eine JTable mit fixierten Spalten aus dem Netz gezogen.
Allerdings hat das Beispiel einen Makel: Die fixierten Spalten reißen beim Anpassen der Spaltenbreite einen Spalt zwischen fixierte und “normale” Spalten, oder schieben sich unter die “normalen” Spalten.
Das was ich brauche wäre, dass sich die Spalten wie bei einer “normalen” Tabelle verschieben und anpassen lassen.
Kann mir jemand dabei helfen? Wo muss ich ansetzen?
