关于java：如何为jtable固定列设置图像，当我运行时，它只获取图像路径

how to set an image for jtable fixed column, when i am running, it's getting an image path only

我创建了一个程序来在 jtable 固定列中设置一个 imageIcon，我创建了一个 jtable 并获取数据库记录，然后将第一列设置为固定列。我在固定列中设置了一个图像图标。当我编译这个程序时，我只得到一个 imageicon 的路径，没有得到一个图像。我在项目包文件夹中修复了一个 imageIcon。

This is the code i used

public void Frm_FlxD_Database() {
try{
TmpRow=0;
TmpMainPrj.PRJ_DB_CONNECTION_ASSGN();
TmpFlxMdl =(DefaultTableModel)FlxD.getModel();
TmpFlxDRow = 0;

TmpFlxSt=TmpGPrjVarDec.GContn.createStatement();
TmpFlxDRs=TmpFlxSt.executeQuery("SELECT * from activitymaster");
PRJ_FLX_DEFTL_ASSGN(FlxD,"BEGIN");
TmpFlxDRs.first();
do {
FlxD.setValueAt(TmpFlxDRs.getString("ACTVTYDESC"), TmpRow,1);
FlxD.setValueAt(TmpFlxDRs.getString("ACTVTYCODE"), TmpRow,2);
FlxD.setValueAt(TmpFlxDRs.getString("DISPSTATUS"), TmpRow,3);
FlxD.setValueAt(TmpFlxDRs.getString("ACTVTYID"), TmpRow,4);
TmpFlxMdl.addRow(new Object[]{""});
TmpRow = TmpRow + 1;
}while(TmpFlxDRs.next());

FRM_FLXD_PTR_DATA_ASSGN(TmpFlxDRow);
}
catch(Exception e){
System.out.println(e);
}
}
private void FRM_FLXD_PTR_DATA_ASSGN(int PFlxRow) {
TmpFlxDRow = PRJ_FLX_PTR_ASSGN(FlxD, PFlxRow, TmpFlxDRow);
}

private int PRJ_FLX_PTR_ASSGN(JTable PFlx, int PCurRow, int PPrvRow) {
ImageIcon TmpIcon;

System.out.println(PCurRow);
System.out.println(PPrvRow);

if (PCurRow != PPrvRow){
TmpIcon = new ImageIcon(getClass().getResource("Blank.gif"));
PFlx.setValueAt(TmpIcon,PPrvRow,0);
System.out.println(TmpIcon);
}
TmpIcon = new ImageIcon(getClass().getResource("Pointer.gif"));
PFlx.setValueAt(TmpIcon,PCurRow,0);
System.out.println(TmpIcon);
return(PCurRow);
}

JTable认识Icon/ImageIcon，简单例子
