how to change JTable Background Color default to white?
提问by manav
I have a JTable that I am displaying in a JScrollpane. The JTable only displays a few rows of information in its grid. The space below the grid to the bottom of the JPanel, that contains the JScrollpane, (Which in turn contains the JTable) is colored solid gray. I'd like to change that color to white. I tried setting the JTable's background color to white, [using the method setBackground(Color,WHITE) ] but that didn't work.
我有一个 JTable 显示在 JScrollpane 中。JTable 仅在其网格中显示几行信息。网格下方到 JPanel 底部的空间，包含 JScrollpane，（又包含 JTable）是纯灰色的。我想把那个颜色改成白色。我尝试将 JTable 的背景颜色设置为白色，[使用方法 setBackground(Color,WHITE) ] 但这没有用。
Can anyone tell me which method to use to change that gray to white?
谁能告诉我使用哪种方法将灰色变为白色？

depend of your code
取决于你的代码
JTable#setFillsViewportHeight(true);
JTable#setFillsViewportHeight(true);
or
或者
JScrollPane#getViewport().setBackground(JTable#getBackground());
JScrollPane#getViewport().setBackground(JTable#getBackground());
or you can to fits JScrollPanes JViewportto the JTables viewby
或者你可以配合JScrollPanes JViewport到JTables view由
JTable#setPreferredScrollableViewportSize(JTable#getPreferredSize());
JTable#setPreferredScrollableViewportSize(JTable#getPreferredSize());

All you have to do is to get the JViewport of the JScrollPane in your JTable and set its background color.
您所要做的就是在 JTable 中获取 JScrollPane 的 JViewport 并设置其背景颜色。
JTable table=new JTable(model);
JScrollPane scroll=new JScrollPane(table);
scroll.getViewport().setBackground(Color.WHITE);
Hope that gives a solution, for making your remaining table space as WHITE.
希望给出一个解决方案，使您剩余的表空间为白色。
