Data partition in an excel row

Question

I have an excel,where near about 156 columns and 2000 rows.Here 36 tasks are being audited,where each taks has been described by 4 columns - say "Task1 Name","Task1 Start Date","Task1 Completion Date","Total Time Spent in Task1".Now some times each of such 4 columns can have values for all and some times all the 4 columns dodes not have values to it.Now Goal is to find out such a 4-tuple set where atleast a single column data present.But if the data is not present then it will be told as unwanted set.So i need such unwanted columns to get moved one side and the partially filed or fullyfiled data in one side.But Non null dataset will move from right to left if its immediate preceded has 4 blank columns,otherwise or not. Find the input table below:

But this is code no way producing correct data output..Please help me here

This code shifts all 'populated' tasks to the left:

Sub ShiftTasks()

    Dim wst As Excel.Worksheet
    Dim lRow As Long
    Dim lTask As Long
    Dim lCol As Long

    Const NUM_TASKS As Long = 36
    Const COL_FIRST As Long = 12

    Set wst = ActiveSheet

    With wst

        For lRow = 2 To .UsedRange.Rows.Count
            lTask = 1
            Do While lTask <= NUM_TASKS
                lCol = COL_FIRST + (lTask - 1) * 4
                If Len(.Cells(lRow, lCol).Value) = 0 And _
                   Len(.Cells(lRow, lCol + 1).Value) = 0 And _
                   Len(.Cells(lRow, lCol + 2).Value) = 0 And _
                   Len(.Cells(lRow, lCol + 3).Value) = 0 Then
                    ' make sure there is something to the right to shift over
                    If .Cells(lRow, lCol).End(xlToRight).Column < .Columns.Count Then
                        ' delete the empty cells and shift everything left``
                        .Range(.Cells(lRow, lCol), .Cells(lRow, lCol + 3)).Delete Shift:=xlToLeft
                    Else
                        ' force the loop to the next row
                        lTask = NUM_TASKS + 1
                    End If
                Else
                    lTask = lTask + 1
                End If
            Loop
        Next lRow
    End With

End Sub
