Cant apply table style in word doc using docx python

Question

I cannot apply a custom table style to a WORD doc using python 3.4. I followed a great method by @scanny: I created a blank WORD doc, created a custom table style and saved it as "OR". I created a new table and applied the custom table style to it. I then deleted the table and saved the doc as "template.docx. I then applied the style as follows:

document = Document("C:/pytest/template.docx")
table = document.add_table(rows=1, cols=3)
table.style = "OR"
hdr_cells = table.rows[0].cells
hdr_cells[0].paragraphs[0].add_run('Date Filmed:').bold = True
hdr_cells[2].paragraphs[0].add_run('Barcode Number:').bold = True
row_cells = table.add_row().cells
row_cells[0].text = date
row_cells[2].text = bcode

When I run the program, it gets an error: File "C:\Python34\lib\site-packages\python_docx-0.8.5-py3.4.egg\docx\styles\styles.py", line 57, in getitem raise KeyError("no style with name '%s'" % key) KeyError: "no style with name 'Title'"

It is not specifying a line in the code, but a file named "styles.py". Do I have the syntax wrong?

thanks, Jeff

Answer 1

Old thread, still a problem. The problem lies in "document". Your template.docx doesn't use the "OR" style and so it's not saved there. Instead, use a generic, empty document i.e. generic_document=Document() and then reference that for your styles table.style = generic_document.styles['OR'].

You need to specify a style object when you are setting table.style = "OR".

So, what you would do to make this works is table.style = document.styles['OR']

The most concise way to do this would be to specify the style when you are creating the table such as: table = document.add_table(rows=1, cols=3, document.styles['OR'])
