Assuming you've done your research and know how to use custom cell renderers, the basic concept is simple.

public Component getTableCellRendererComponent(
                        JTable table, Object color,
                        boolean isSelected, boolean hasFocus,
                        int row, int column) {
    // Prepare renderer as usual...

    // Check to see if the current row/column is within 
    // the acceptable range...
    // It would be usful if this information was coming from
    // some kind of model
    if (row == iconRow && column == iconColumn) {
        // Apply the icon for this cell renderer
    }
    return this;
}
