Hallo,

ich möchte ich in einer Tabelle einzelne Zellen einfärben. Jedoch funktioniert es nicht so wie ich es mir vorgestellt habe. Ich schaffe es, dass ich in die betreffenden Bereiche Strings einfügen kann, aber nicht diese einzufärben. Ich hoffe, dass ihr mir helfen könnt.

So sieht es zur Zeit aus:

Das ist mein Code:

                    TestTabelle frame = new TestTabelle();
                    frame.setVisible(true);
                } catch (Exception e) {
                    e.printStackTrace();

Hi,
sry vllt habe ich es schlecht formuliert. Da wo "X" steht soll die Zelle eingefärbt sein. Ich möchte, dass ich im Code angeben kann z.B. in der Zeile 1 sollen die Zellen der Spalten 1 bis 21 blau eingefärbt sein.

LG
