I wish to use some tabspace in my JTextPane using html, how can i do it ?
I tried the Java way with putting \t, however that seems not to work.

this is my code:

```
JTextPane pane = new JTextPane();
pane.setContentType("text/html");
String ausgabe = "hello world";
HTMLDocument doc=(HTMLDocument) pane.getStyledDocument();
doc.insertAfterEnd(doc.getCharacterElement(doc.getLength()),"<b>"+ausgabe"+"<br></b>");

```
