BIRT报表script

1.隔行高亮显示

1. 在布局（Layout）中,选择Table－Detail的行。如下图：

2. 然后选择Script，打开脚本窗口顶部的方法列表并选择onPrepare，如图所示。

var count=0;

3. 最后打开脚本窗口顶部的方法列表并选择 onCreate，如图所示：

count++;
if (count % 2 != 0) {
  style.setBackgroundColor(silver);
 }

4. 保存，点击Preview预览结果如下图。

这是网上找别人的案例来的，然后就照着做，就出现问题了

报了一大堆问题：

又到网上搜了，然后就说:

不是在明细行的script里定义count,定义count也不能使用var哦。
要在表格的onprepare里定义count=0;

貌似在明细里还是在表格的script定义都一样，然后把它修整过来，竟然可以了。
