Append text to certain columns in java text area

How do I append text to certain columns in java text area. I've set the columns to 2 but I want to append one text on 1 column and another text on the other column. How do I do开发者_开发问答 that?

jTextArea1.append("\n");
jTextArea1.setColumns(2);

jTextArea1.append("a");
jTextArea1.append("\n");
jTextArea1.append("b");

JTable might be a better choice for columnar data.

Although it sound like setColumns sets the number of textual columns on a JTextArea what it really does is defining the number of single-character columns for calculating the preferred size of the text area. E.g. if you specify setColumns(80) the preferred size is calculated to be at least 80 characters wide (if I remember correctly calculated as eighty times the with of 'm').

If you want to have multiple text columns you might use a JTable as trashgod proposed or use two textareas side by side (if you put both within a scrollpane they will also scroll simultaneously).
