JTable Won't Allow Editing Despite isCellUpdatable is Set to Return True

Question

Mass apologies if I somehow sent this to the wrong forum by mistake. However, aid from the local Java gurus would be much appreciated since I'm the only Java programmer at this company, so I don't have anyone to really ask for advice or anything.
I've been trying to enter an updatable ResultSet into a JTable for about a week now, but the issue I ended up running into was that if you click on a cell with the intention to edit the contents, it won't even highlight the cell, much less let you edit it.
I've searched Google and this forum along with tried to hunt down more complex books on Java rather than your standard "So you want to learn Java" cookbooks, but I've come up with null. I've also created about five different variations of TableModels for the purposes of handling this, including one that used an array of Objects instead of the ResultSet, but the problem persists.
Here is the latest version of the TableModel that I've come up with
package EventCalGUI;
import javax.swing.table.AbstractTableModel;
import EventCalSQL.TableData;
@SuppressWarnings("serial")
public class UpdateRSModel extends AbstractTableModel
     /** <code>TableData</code> from database */
     private TableData data;
     public UpdateRSModel(TableData tdata)
          data = tdata;
     @Override
     public int getColumnCount()
          return data.getColCount();
     @Override
     public int getRowCount()
          return data.getRowCount();
     @Override
     public Object getValueAt(int row, int col)
          return data.getValue(row, col);
     @Override
     public boolean isCellEditable(int row, int col)
          return true;
     @SuppressWarnings("unchecked")
     @Override
     public Class getColumnClass(int col)
          return data.getColClass(col);
     @Override
     public String getColumnName(int col)
          return data.getHeader(col);
     @Override
     public void setValueAt(Object value, int row, int col)
          data.setValue(value, row, col);
}The reason for suppressing the warnings is because Eclipse attempts to be too helpful with its cautions and I was sick of seeing a long list of unnecessary yellow caution signs.
This is the TableData class that the above TableModel derives from. I hadn't added in the actual ResultSet updating capabilities until I was sure I could get the JTable to work.
package EventCalSQL;
import java.sql.*;
public class TableData
     Object[][] data = null;
     String[] headers = null;
     int rows = 0;
     int cols = 0;
     @SuppressWarnings("unchecked")
     Class[] colclass = null;
     public TableData (ResultSet rs)
          try
               ResultSetMetaData metadata = rs.getMetaData();
               // -------------- SET COLUMN DATA ---------------
               cols = metadata.getColumnCount();
               headers = new String[cols];
               colclass = new Class[cols];
               String classname = "";
               for (int b = 0; b < cols; b++)
                    headers[b] = metadata.getColumnName(b + 1);
                    classname = metadata.getColumnClassName(b + 1);
                    colclass[b] = Class.forName(classname);
               // ------------ SET ROW DATA --------------
               if (rs.last())
                    rows = rs.getRow();
                    rs.beforeFirst();
               if (rows != 0)
                    data = new Object[rows][cols];
                    for (int i = 0; i < rows; i++)
                         rs.absolute(i + 1);
                         for (int a = 0; a < cols; a++)
                              data[i][a] = rs.getObject(a + 1);
          catch (SQLException sql)
               // I'M UNINTERESTING!
          catch (ClassNotFoundException cnf)
               // BE BORED!
          catch (NullPointerException np)
               // I'M BORING!
     public Object getValue(int row, int col)
          return data[row][col];
     public String getHeader(int col)
          return headers[col];
     public void setValue(Object value, int row, int col)
          data[row][col] = value;
     public int getRowCount()
          return rows;
     public int getColCount()
          return cols;
     @SuppressWarnings("unchecked")
     public Class getColClass(int col)
          return colclass[col];
}I've checked the exceptions, and they work. I just added into the comments since nothing's really supposed to happen there if it's an empty set. I just have a weird sense of humor after twenty-plus hours of coding variations of the same thing over and over.
Thank you very much for any and all help ahead of time!

Answer 1

Hidralisk: Thank you for the suggestion, but that's not the problem I'm running into. I really appreciate you trying to help though.
camickr: I'll double-check my code to see where I might've unintentionally strayed from your suggestion. I deeply appreciate the help.

Haven't had the time to double-check my code since I've been re-assigned to other projects (the joys of being the solo Java programmer here), but I awarded you the points, camickr, since your suggestion seems to be the one that could've put me on the right track. Thanks so much for your help.
