JTable刷新

我使用带有水平和垂直滚动条的 JTable。我的 JTable 在包含数据的行之后有空白空间。当我打开位于表格下方的面板时，它隐藏了 JTable 的一部分，并且滚动出现在 JTable 上。这是正常行为，但是当我关闭该面板时，没有数据的空白空间变成灰色而不是白色。仅当我的 JTable 上有水平滚动条时才会发生这种情况。我想我必须强制 JTable 重新绘制，我在 TableHeader 和 JTable 上尝试了 resizeAndRepaint() 但它不起作用。

请帮忙！谢谢！如果对表执行任何调整大小操作，则会调用以下 resize() 代码

for (int i = 0; i < columsNum; i++){
        TableColumn column = this.getColumnModel().getColumn(i);
        int preferedSize = //current size
        int minimumSize = // min size
        if (minimumSize != ColumnSizeCalculator.UNDEFINED_WIDTH)
            column.setMinWidth(minimumSize);            
        column.setPreferredWidth(preferedSize);        
    }   

    this.revalidate();
    this.repaint();

原文

I use JTable with horizontal and vertical scrollbars. My JTable has empty space after rows with data.
When I open panel that is situated down of my table it hides a part of JTable and scrolling appears on JTable. This is normal behavior, but then I close that panel, empty space without data becomes grey instead of white color.
This only happens when I have horizontal scrollbar on my JTable. I suppose I must force JTable to repaint, I tried resizeAndRepaint() on TableHeader and JTable but it didn't work.

Please help! Thanks!
Here is resize() code invoked if any resize action was performed on table

for (int i = 0; i < columsNum; i++){
        TableColumn column = this.getColumnModel().getColumn(i);
        int preferedSize = //current size
        int minimumSize = // min size
        if (minimumSize != ColumnSizeCalculator.UNDEFINED_WIDTH)
            column.setMinWidth(minimumSize);            
        column.setPreferredWidth(preferedSize);        
    }   

    this.revalidate();
    this.repaint();
