optimize code if possible

Hi all,
good morning

I aim to populate word existing table from an excel rang.
I'd prefer to use excel range to array and pass it to the word table rather than copy each cell and paste it to word table.
then I come up with this code hope to have help to optimize
I was trying for this method but I faild

   wdDoc.Tables(1).Cell(i, j).Range = array(i,j)

then I come up with this code, hope to have help to optimize

Sub xl_Rng2Word_table()

    Dim appWord As Word.Application
    Dim wordDoc As Word.Document
    Dim rng As Range
    Dim sh_source As Worksheet
    Dim wdApp As Word.Application
    Dim wdDoc As Word.Document

    Set sh_source = ThisWorkbook.Sheets("sheet1")
    Set rng = sh_source.Range("a1:j21")
    vaData = rng
    u = UBound(vaData, 1)
    l = UBound(vaData, 2)


    Set wdApp = New Word.Application
    wdApp.Visible = True
    Set wdDoc = wdApp.Documents.Open(ThisWorkbook.Path & "\" & "3333.docx")
    j = 1
    For Each Cel In wdDoc.Tables(1).Range.Cells
        i = i + 1
        Count = Count + 1
        Cel.Range.Text = vaData(j, i)
        If i = l Then
            i = 0
            j = j + 1
        End If
        If j = u + 1 Then Exit For
    Next Cel

End Sub
