This should work smoothly (if the vectors in each column have the same size) :
Sub test_gmeroni()
Dim TempTable() As Variant, _
wS As Worksheet, _
Rg As Range, _
InBound As Long, _
i As Long, _
j As Long
Set wS = ThisWorkbook.Sheets("OutPut")
Set Rg = wS.Range("A1")
ReDim TempTable(1 To 7576, 1 To 3)
For i = LBound(TempTable, 1) To UBound(TempTable, 1)
For j = LBound(TempTable, 2) To UBound(TempTable, 2)
'Calculate vectors size
InBound = UBound(TempTable(i, j), 1)
'Put vector on sheet
Rg.Offset(0, j - 1).Resize(InBound, 1).Value2 = TempTable(i, j)
Next j
'Select next cell to start printing next row
Set Rg = Rg.Offset(InBound + 1, 0)
Next i
End Sub
