I wish this helpful for you I have two tables T1 with columns Id. It has 5 values , Use a partitioned outer join:
code :
SELECT t2.weekno,
       t1.id,
       COALESCE( t2.cnt, 0 ) AS cnt
FROM   T1
       LEFT OUTER JOIN T2
       PARTITION BY ( T2.weekno )
       ON (T1.id = T2.id);
WEEKNO | ID | CNT
-----: | -: | --:
    40 |  1 |  10
    40 |  2 |  11
    40 |  3 |   0
    40 |  4 |   0
    40 |  5 |   0
    41 |  1 |  13
    41 |  2 |  12
    41 |  3 |  14
    41 |  4 |   0
    41 |  5 |   0
    42 |  1 |  16
    42 |  2 |  15
    42 |  3 |  17
    42 |  4 |  18

will be helpful for those in need It's not stacking it side but side, but the short cut of Ctrl-r lets you show / hide the results window very quickly, and not bother moving the vertical divider.

this one helps. , Try to use Date part of filtered dates:
code :
Calls.Count(call => call.OutcomeActionDate.Value >= fourWeeksStartDate.Date &&
                    call.OutcomeActionDate.Value < threeWeeksStartDate.Date &&
                    call.UserId == user.UserId);

this one helps. For now, wrap a CAST to VARCHAR around the STUFF part of the query from your previous question, i.e.:
code :
SELECT 
      t.CUSTOMER, 
      SUM(t.REVENUE) as REVENUE,
      CAST(
          STUFF(
                  (
                     SELECT ',' + Cast(s.work_order as varchar)
                     FROM tblname s
                     WHERE s.CUSTOMER = t.CUSTOMER
                     FOR XML PATH('')
                  ),1,1,''
          ) AS VARCHAR
      ) AS [WORK Order]
FROM tblname t
Group BY CUSTOMER

C# SQL query output to Excel not including newly added fields in output

it helps some times First up, I second the comment about using EPPlus. I think it even has a method to turn a datatable into a sheet, so this click event handler could be boiled down to about 4 lines of code. Take a look over this SO question - Export DataTable to excel with EPPlus
Second, I think your actual problem is a simple off-by-one error
code :
for(int col = 1; col < table.Columns.Count; col++)
for(int col = 1; col <= table.Columns.Count; col++)
for(int col = 0; col < table.Columns.Count; col++)
  excel[row, col+1] = table[row][col]; //excel is 1 based, c# is 0 based
using(SqlDataAdapter da = new SqlDataAdapter("SELECT * FROM services", "PUT YOUR CONN STRING IN A CONFIG FILE")){
    DataTable dt = new DataTable();
    da.Fill(dt);
    using (ExcelPackage ep = new ExcelPackage(newFile))
    {
      ExcelWorksheet ws = ep.Workbook.Worksheets.Add("Sheetname");
      ws.Cells["A1"].LoadFromDataTable(dt, true);
      ep.SaveAs(new FileInfo("YOUR SAVE PATH HERE"));
    }
}

Any of those help Use correlated subqueries within your queries by common column filmID to produce new columns :
code :
SELECT film, 
       (SELECT image FROM tblfilmimage WHERE imageID=1 and filmID = f.filmID ) as image1, 
       (SELECT image FROM tblfilmimage WHERE imageID=2 and filmID = f.filmID ) as image2
  FROM tblfilm f
 WHERE f.filmID = 2;
SELECT film, 
       MAX(CASE WHEN i.imageID=1 THEN i.image END ) as image1, 
       MAX(CASE WHEN i.imageID=2 THEN i.image END ) as image2
  FROM tblfilm f
  JOIN tblfilmimage i on i.filmID = f.filmID
 WHERE f.filmID = 2
 GROUP BY film;
