如何结合两个查询和输出结果是水平的

Question

我有两个表记录了月度津贴和OT津贴，这两个表都有Department列和Track列 我需要所有部门的报告，但要与跟踪列“ DL”，“ IDL”分开

我只能执行一个跟踪，但不能在一个查询中与跟踪列结合 这是我的代码

conn.Open

Monthly_Table

;WITH sums AS 
(
   SELECT
      sum(Monthly.Pay) as Total_Monthly,OT.MealAllowance_OT,Monthly.Dept_Id,Monthly.Dept_Name

   FROM
     [dbo].[SPCM_TX_MonthlyAllowance] as Monthly
     left join (  select Period,sum(MealAllowance_OT) MealAllowance_OT,Dept_Id
   from [dbo].[SPCM_Cal_OTLog]
   where Track = 'IDL'
   group by Period,Dept_Id) OT
   on Monthly.Dept_Id = OT.Dept_Id  
   where Monthly.Track = 'IDL'
   GROUP BY
      Monthly.Dept_Id, Monthly.Dept_Name,MealAllowance_OT,Monthly.Track
)
SELECT   
   Dept_Id,Dept_Name,Total_Monthly,MealAllowance_OT,Total_Monthly+MealAllowance_OT AS 'GrandTotal' 
FROM 
   sums  
   order by GrandTotal desc

OT_Table

2           IDL      2019-10-10     400       1A           A
3           DL       2019-10-10     400       1B           B
4           IDL      2019-10-10     400       1B           B
