# You don't necessarily need to use the functions and classes that PyLaTeX provides.
# You can add any arbitrary text or LaTeX code to your document as strings using the NoEscape wrapper
# Eg
doc.append(NoEscape(r'egin{tabular}{ll}'))
doc.append(NoEscape(r'Entry{abc}{123}'))
doc.append(NoEscape(r'end{tabular}'))
