The better choice is to use a JTable. Read the section from the Swing tutorial on How to Use Tables for more information and working examples.

If you must use a JTextArea, then you need to use a monospaced font.

textArea.setFont( new Font("monospaced", Font.PLAIN, 10) );

or any other font that that has a fixed size for each character.

I would use a JEditorPane here with "text/html" content type and make an HTML table.

Of course, you have to use a fixed-width-font. But detecting one which works for all characters is not trivial (or impossible?), because, e.g., Asian characters usually are two latin characters wide.

Use a Formatter object.
