The Question:
Which is the simplest way to display an Image in a JTable?

Hi.. mathuoa
You can set the row height as:
table.setRowHeight(300);
Here's the abstract table model implementaion e.g.
* Implementation of abstract table model for displaying Image(s) in table
* Cell grid.
* @version 1.0 10 Sep 2002
* @author Md. Ash-Shakur Rahaman (mailto: [email protected])
class GridImageTableModel extends AbstractTableModel{
/** Number of rows */
static int rows;
/** Number of columns*/
static int cols;
/** table data */
public static Object[][] rowData;
/**column names */
String[] colNames;
* Constructor
* @param     rd     row data as 2D Object array
* @param     cn     column names as 1D String array
public GridImageTableModel(Object[][] rd, String[] cn){
this.rowData = rd;
this.colNames = cn;
* gets the number of rows available of the table
* @param     nothing no parameter is required
* @return rows     returns the rows count as int
public int getRowCount(){
this.rows = rowData.length;
return rows;
* gets the number of columns available of the table
* @param     nothing     no parameter is required
* @return cols     returns the column count as int
public int getColumnCount(){
this.cols = colNames.length;
return cols;
* gets the data at particular row & column
* @param     row     at which row
* @param     col     at which column
* @return rowData the data as 2D Object array
public Object getValueAt(int row, int col){
return rowData[row][col];
* gets the class name of a particular column
* @param     c     column number for which the class names is to be determined
* @return     class     returns the class name of the column
public Class getColumnClass(int c){
return getValueAt(0,c).getClass();
* gets the column cell editable or non editable
* @param row     which row
* @param col     which column
* @return editable true if editable;
* false otherwise     
public boolean isCellEditable(int row, int col){
return true;
* sets the value at particular row-column
* @param value     value to be inserted
* @param row     at which row
* @param col     at which column
* @return nothing
public void setValueAt(Object value, int row, int col){
rowData[row][col] = value;
fireTableCellUpdated(row,col);
* Implementation of Default table column model for displaying Image(s) in table
* Cell grid.

class GridImageTableColModel extends DefaultTableColumnModel{
/**column names*/
String [] colNames;
/**column counter*/
static int counter=0;
* GridImageTableColModel constructor with column names
* @param cn coumn names as 1D String array
public GridImageTableColModel(String[] cn){
this.colNames = cn;
* adds column to the table
* @param tc table column
* @return nothing
public void addColumn(TableColumn tc){
// if counter is equal to the number of column then reset counter to zero
if (counter == 1) counter=0;
tc.setHeaderValue(DataStoreUnit.grdimgColumnNames[counter]);
tc.setResizable(false);
super.addColumn(tc);
counter+=1;
Use this as follwoung manner:
//Grid Image Table Implementation
final static String[] grdimgColumnNames = {"Image(s)"};
// Initial data to be displayed in the table
final Object[][] grdimgData = {{""}};
//Grid Image Table Model: Table to display the data
TableModel grdimgTableModel = new GridImageTableModel(grdimgData,grdimgColumnNames);
//Grid text Table Header
JTableHeader grdimgTableHeader = new JTableHeader();
// Grid image Column Model
TableColumnModel grdimgTableColumnModel = new GridImageTableColModel(grdimgColumnNames);
// Grid Image Table
JTable grdimgtable = new JTable(grdimgTableModel);
JScrollPane jspGridImageTable = new JScrollPane();
int tab = grdimgtable.AUTO_RESIZE_ALL_COLUMNS;
grdimgTableHeader.setResizingAllowed(false);
grdimgTableHeader.setBackground(new Color(0, 0, 239));
grdimgTableHeader.setForeground(Color.white);
grdimgTableHeader.setFont(font);
grdimgTableHeader.setColumnModel(grdimgTableColumnModel);
grdimgtable.setTableHeader(grdimgTableHeader);
grdimgtable.createDefaultColumnsFromModel();
grdimgtable.sizeColumnsToFit(tab);
grdimgTableHeader.setReorderingAllowed(false);
grdimgtable.setRowHeight(300);
/**render the first cell in the table*/     
grdimgTableCellRender(grdimgtable.getColumnModel().getColumn(0));
grdimgtable.setPreferredSize(new Dimension(32767,32767));
jspGridImageTable.getViewport().add(grdimgtable, null);
grdimgtable.setBorder(new LineBorder(Color.blue));
I think now you can work...Go ahead..
