java.lang.ArrayIndexOutOfBoundsException: 0 >= 0 attempting to populate JTable

I'm subclassing JTable and using a DefaultTableModel to model my table data. The following class sets up the JTable, and adds one row to the model.

import java.io.File;
import java.util.Iterator;
import java.util.Vector;

import javax.swing.JTable;  
import javax.swing.table.DefaultTableModel;
import javax.swing.table.TableColumn;

public class SelectedFileTable extends JTable {
Vector<File> SelectedFiles = new Vector<File>(); 
DefaultTableModel Model    = new DefaultTableModel();

TableColumn ColumnName     = new TableColumn();
TableColumn ColumnSize     = new TableColumn();
TableColumn ColumnRmIcon   = new TableColumn(); 

ImageFilenameFilter Filter = new ImageFilenameFilter();

public SelectedFileTable() {
    super();
    this.setModel(Model);

    ColumnName.setHeaderValue(new String("Name") );
      ColumnName.setMinWidth(200);
    ColumnSize.setHeaderValue(new String("Size") );
      ColumnSize.setMinWidth(50); 
      ColumnSize.setMaxWidth(100);
    ColumnRmIcon.setHeaderValue(new String("Remove?") );
      ColumnRmIcon.setMaxWidth(100);
      ColumnRmIcon.setResizable(false);

    this.addColumn(ColumnName);
    this.addColumn(ColumnSize);
    this.addColumn(ColumnRmIcon);

    this.setShowVerticalLines(false);
    this.setShowHorizontalLines(true);
this.setAutoCreateColumnsFromModel(true);

this.addFile( new File("C:/temp/cfk.jpg") );
}
public void addFile(File file) {
    System.out.println("FileTable adding: " + file.getName() );
    if ( file.isDirectory() ) { 
        for ( File f : file.listFiles(Filter) ) {
            this.addFile(f);
        }
    } else { 
        if ( Filter.accept(file) ) {
            System.out.println("Accepting file; " + file.getName() );
            SelectedFiles.add(file);
            {
                String name = file.getName();
                Long size = new Long( file.length() );
                String tempstr = new String("X");

                System.out.println("RowItems before: " +
