copied!<p>Here's a code snippet that I put together for a project that I was working on. The code has been tested and verified for a table that has non-editable cells in the first and last column. The class restricts tabbing to only the editable cells of the table. It also supports shift-tabbing to tab in reverse.</p> <pre><code>public class JTableCellTabbing { /** * * Creates a new {@code JTableCellTabbing} object. * * */ private JTableCellTabbing() { } /** * * Set Action Map for tabbing and shift-tabbing for the JTable * * * @param theTable - Jtable with NRows and MCols of cells * @param startRow - valid start row for tabbing [ 0 - (numRows-1) ] * @param numRows - Number of rows for tabbing * @param startCol - valid start col for tabbing [ 0 - (numCols-1) ] * @param numCols - Number of columns for tabbing */ @SuppressWarnings("serial") static public void setTabMapping(final JTable theTable, final int startRow, final int numRows, final int startCol, final int numCols) { if (theTable == null) { throw new IllegalArgumentException("theTable is null"); } // Calculate last row and column for tabbing final int endRow = startRow + (numRows - 1); final int endCol = startCol + (numCols - 1); // Check for valid range if ((startRow > endRow) || (startCol > endCol)) { throw new IllegalArgumentException("Table Size incorrect"); } // Get Input and Action Map to set tabbing order on the JTable InputMap im = theTable.getInputMap(JTable.WHEN_ANCESTOR_OF_FOCUSED_COMPONENT); ActionMap am = theTable.getActionMap(); // Get Tab Keystroke KeyStroke tabKey = KeyStroke.getKeyStroke(KeyEvent.VK_TAB, 0); am.put(im.get(tabKey), new AbstractAction() { @Override public void actionPerformed(ActionEvent e) { int row = theTable.getSelectedRow(); int col = theTable.getSelectedColumn(); col++; // Move to next row and left column if (col > endCol) { col = startCol; row++; } // Move to top row if (row > endRow ) { row = startRow; } // Move cell selection theTable.changeSelection(row, col, false, false); } }); // Get Shift tab Keystroke KeyStroke shiftTab = KeyStroke.getKeyStroke(KeyEvent.VK_TAB, java.awt.event.InputEvent.SHIFT_DOWN_MASK); am.put(im.get(shiftTab), new AbstractAction() { @Override public void actionPerformed(ActionEvent e) { int row = theTable.getSelectedRow(); int col = theTable.getSelectedColumn(); col--; // Move to top right cell if (col < startCol) { col = endCol; row--; } // Move to bottom row if (row < startRow ) { row = endRow; } // Move cell selection theTable.changeSelection(row, col, false, false); } }); } </code></pre> <p>}</p> <p>And here's how the class is used for your table:</p> <pre><code>JTable myTable = new JTable(); // Set up table attributes.... JTableCellTabbing.setTabMapping(myTable, 0, NUM_ROWS, 1, (NUM_COLS-1)); </code></pre>
