SSRS格式化表结构

Question

我有一张显示人口信息的人口统计详细信息表。字段是

• ID - 唯一ID字段（自动增量）
• 人口 - 整数
• SurveyDate - datetime字段
• 城市 - 指示城市的varchar字段
• 州 - varchar
• 地区 - 南/北
• 国家/地区

我需要有报告以下列格式显示人口详细信息

India              Current Yr Figure        PreviousYr Figure   
State_1            X,XX,XX,XXX              XX,XX,XXX 
State_2            X,XX,XX,XXX              XX,XX,XXX 
State_3            X,XX,XX,XXX              XX,XX,XXX 

我尝试过以下查询：

WITH cte AS (
    SELECT TOP (99.99) PERCENT 
            Population, City, State, SurveyDate, Region, Country, 
            CASE WHEN (DATEPART(yyyy, surveydate) = DATEPART(yyyy, GETDATE()))THEN 'CurrentYear' ELSE NULL END AS CurrentYear, 
            CASE WHEN (DATEPART(yyyy, surveydate) <> DATEPART(yyyy, GETDATE())) THEN 'LastYear' ELSE NULL END AS LastYear
    FROM DemographicDetails
    ORDER BY City)  
SELECT Population, City, State, Region, Country, SurveyDate, 
       CurrentYear, LastYear, COALESCE (CurrentYear, LastYear) AS DateStatus
FROM cte AS cte_1

在报告文本框中，我将表达式表示为：

iif(Fields!DateStatus.Value="CurrentYear",Fields!Population.Value,0) 

在第一个文本框和第二个框中，表达式为：

iif(Fields!DateStatus.Value="LastYear",Fields!Population.Value,0)

但是，我的结果与此类似：

India       Current Yr Figure     PreviousYr Figure          
State_1     value1                0
State_1     0                     value2
State_2     value3                0 
State_3     value4                0

但我需要如下：

India               Current Yr Figure         PreviousYr Figure          
State_1             value1                    value2
State_2             value3                    0 
State_3             value4                    0

，即同一行中的state_1 value1和value2。
