Python-docx Copy Table

I have the following code which I am using to save a table, modify the table, and then make a copy of the table. I got copy_table_after() from Here.

def copy_table_after(table, paragraph):    tbl, p = table._tbl, paragraph._p    new_tbl = deepcopy(tbl)    p.addnext(new_tbl)def replaceText(document, search, replace):    for table in document.tables:        for row in table.rows:            for paragraph in row.cells:                if search in paragraph.text:                    paragraph.text = replacedocument = Document('Test.docx')template = document.tables[0]replaceText(document, '<<VALUE_TO_FIND>>', 'New value')paragraph = document.add_paragraph()copy_table_after(template, paragraph)

My problem is that when I run copy_table_after, it copies the table with the new text. Is there a way to 'save' the table and then make a copy of the original table after I have already made changes to it?
