我的报告中有一个名为的列totalhours，我想将颜色设置为yellow当名为的列的值为outtimeis时null。因此，为此我创建了具有以下详细信息的条件样式：

<style name="TotalHoursBackColor" lineSpacing="Single">
   <conditionalStyle>
      <conditionExpression><![CDATA[new Boolean($F{Out_time}.equals( null ))]]>  </conditionExpression>
      <style mode="Opaque" backcolor="#FFFF33" lineSpacing="Single"/>
   </conditionalStyle>
</style>

上面的代码给出了以下输出

编号 empid intime outtime totalhours
1 100 9:00 13:00 4:00

2 101 9:10 空黄色

3 105 9:30 13:30
                      14:30 空     

4 103 9:30 18:30 9:00

5 107 9:40 13:40 8:00
                      14:40 18:40    

6 108 10:00 空黄色

7 106 10:00 13:00
                      14:00 空

但是，我希望输出如下：

编号 empid intime outtime totalhours
1 100 9:00 13:00 4:00

2 101 9:10 空黄色

3 105 9:30 13:30 黄色
                      14:30 空      

4 103 9:30 18:30 9:00

5 107 9:40 13:40 8:00
                      14:40 18:40    

6 108 10:00 空黄色

7 106 10:00 13:00 黄色
                      14:00 空

您应该将带有样式文本（带有$F{TotalHours}表达式）的textField的评估时间属性更改为Band值。

工作样本。

输入数据，csv数据源：

EmployeeID,In_time,Out_time,TotalHours,FirstName,LastName,EmployeeNo
101,9:00,13:00,4:00,Filippo,Inzaghi,1
102,10:00,,,Zineddin,Zidan,2
