我正在测试表模型和渲染。但是我在调整列宽方面遇到了一些问题，我无法调整列宽，因为它是内容文本。我使用了JWindow并隐藏了JFrame。我想调整这个表的列宽，因为我喜欢........ 但我不能使用这段代码.......
for(int i=0;i<header.length;i++){
TableColumn col=table.getColumnModel().getColumn(i);
if(i==0)
col.setWidth(106);
if(i==1)
col.setWidth(157);
if(i==2)
col.setWidth(103);
if(i==3)
col.setWidth(103);
}
这是我的全部代码....检查一下......请............
