If we can assume the userform is in Word then

Private Sub CommandButton1_Click()
Dim oDoc As Document
Dim oTbl As Table
Dim oRng As Range
    Me.Hide
    'The following template must exist at the named location
    Set oDoc = Documents.Add("C:\Users\Username\Desktop\Template 1.dotx")
    Set oRng = oDoc.Range
    Set oTbl = oDoc.Tables.Add(Range:=oRng, _
                               NumRows:=3, _
                               NumColumns:=4, _
                               DefaultTableBehavior:=wdWord9TableBehavior)
    oTbl.Range.Cells(1).Range.Text = Me.TextBox1.Text
    'Move the start of the range to the end of the document
    oRng.Collapse 0
    oRng.Text = "This is after the table"
lbl_Exit:
    Exit Sub
End Sub
You asked earlier what I meant by
"Unload the form in the main code when you have finished with it and not in the userform code."
I meant that I would call the userform from a macro that would do all the processing e.g.

Option Explicit
Sub ProcessDocument()
Dim oFrm As New UserForm1        'The name of the userform
Dim oDoc As Document
Dim oTbl As Table
Dim oRng As Range
    With oFrm
        .Show
        If .Tag = 1 Then
            'The following template must exist at the named location
            Set oDoc = Documents.Add("C:\Users\Username\Desktop\Template 1.dotx")
            Set oRng = oDoc.Range
            Set oTbl = oDoc.Tables.Add(Range:=oRng, _
                                       NumRows:=3, _
                                       NumColumns:=4, _
                                       DefaultTableBehavior:=wdWord9TableBehavior)
            oTbl.Range.Cells(1).Range.Text = .TextBox1.Text
            'Move the start of the range to the end of the document
            oRng.Collapse 0
            oRng.Text = "This is after the table"
        End If
    End With
    Unload oFrm
lbl_Exit:
    Set oFrm = Nothing
    Set oDoc = Nothing
    Set oTbl = Nothing
    Set oRng = Nothing
    Exit Sub
End Sub
and in the userform I would have simply
Option Explicit

Private Sub CommandButton1_Click() 'Continue
    Me.Tag = 1
    Me.Hide
lbl_Exit:
    Exit Sub
End Sub

Private Sub CommandButton2_Click() 'Cancel
    Me.Tag = 0
    Me.Hide
lbl_Exit:
    Exit Sub
End Sub
