我想在特定的JTable 单元格中显示一个图标，而不是在整个列的单元格中显示相同的图标。

假设您已经完成了research 并知道如何使用custom cell renderers，基本概念很简单。

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;
}
