如何在PyLaTeX中将希腊字母编译到表中？

from pylatex import Document, Section, Subsection, Tabular
from pylatex.utils import bold, NoEscape

doc = Document()

with doc.create(Section('Table with Greek Letters')):
    with doc.create(Subsection('Greek Letters')):
        # 添加希腊字母到表中

with doc.create(Tabular('c|c|c|c|c|c|c|c')) as table:
    table.add_hline()
    table.add_row(("Alpha", "Beta", "Gamma", "Delta", "Epsilon", "Zeta", "Eta", "Theta"))
    table.add_hline()
    table.add_row(("Iota", "Kappa", "Lambda", "Mu", "Nu", "Xi", "Omicron", "Pi"))
    table.add_hline()
    table.add_row(("Rho", "Sigma", "Tau", "Upsilon", "Phi", "Chi", "Psi", "Omega"))
    table.add_hline()

doc.generate_pdf('greek_letters_table', clean_tex=False)
