That seems fairly straightforward. Change the path to the location where you want to save the PDF (that path must exist).
Code:
Sub CellToPDF()
'Graham Mayor - https://www.gmayor.com - 04 May 2023
Dim oTable As Table
Dim oCell As Cell
Dim oRng As Range
Dim oDoc As Document, oNew As Document
Dim intPos As Integer
Dim strDocName As String
Const strPath As String = "C:\path\" 'the path where the document is to be saved
If ActiveDocument.Tables.Count < 2 Then GoTo lbl_Exit
Set oDoc = ActiveDocument
Start:
strDocName = oDoc.Name
intPos = InStrRev(strDocName, ".")
If intPos = 0 Then
oDoc.Save
GoTo Start
End If
strDocName = Left(strDocName, intPos - 1)
strDocName = strPath & strDocName & ".pdf"
Set oTable = ActiveDocument.Tables(2)
Set oCell = oTable.Cell(2, 1)
oCell.Select
Selection.Copy
Set oNew = Documents.Add
Set oRng = oNew.Range
oRng.Paste
Debug.Print strPath & strDocName
