One way to figure this out is to browse the JDK source code. In this answer, I assuming you're using JDK 1.4, though the answer should hold for JDK 1.3.

The default editor will take several forms depending on the class contained in the cell. You would change this by calling setDefaultEditor() on the table.

Assuming that the default editor is being used to edit a text cell, it will be a JTextField.

You can retrieve the cell editor for the table by using getCellEditor(), or you can use getDefaultEditor(Class) to retrieve the default editor for a specific class.

So if you have a JTable myTable. Your code might look like the following:
  JTable myTable = new JTable(12, 10);
  // Initialization code goes here

  // Retrieve the Cell Editor for String values.
  TableCellEditor defaultEditor = myTable.getDefaultEditor(String.class);

  // Retrieve the actual Java Component used in editing
  Component editComponent = defaultEditor.getComponent();
 
  // Now set the font that I want to use. Something BIG.
  Font newFont = new Font("TimesRoman", Font.BOLD, 20);
  editComponent.setFont(newFont);

Alternately you can use the UIManager to set the font for the TextFields in your application, and that should also change the font for editing String cells (and also the font for all JTextFields and other things).

The call would be something like:

UIManager.put("TextField.font", new Font("TimesRoman", Font.BOLD, 20));

I hope this helps. To paraphrase a well-known character, my main advice is "Use the source, Luke".

Try setting the font used by the table.
If this doesn't have the desired effect, then you will proabky need to supply your own custom cell editor.

JTable table = new JTable ( .... ) ;
table.setFont ( new Font ( "FontName", Font.STYLE, <size> ) ) ;

"FontName" can be "Default", or "TimesRoman", or one of the available fonts. The STYLE can be BOLD, or PLAIN, or ITALIC, or combined as Font.BOLD | Font.ITALIC. The size should be an integer (try 12 or something close to it).

Mayank.
