Workbook with CellRichText exception

[alxpolyakov]

With code
`blk = TextBlock
font_bold = InlineFont(b=True)
font_normal = InlineFont(b=False)
wb = Workbook()
ws = wb.active
for r in data['requests']:
rich_string = CellRichText(
blk(font_normal, text='Заявка №'),
blk(font_bold, text=str(r['id'])),
blk(font_normal, text=' Мастерская'),
blk(font_bold, text=str(r['shop']['sort'])),
blk(font_normal, r['shop']['name'])
)
ws['A%s' % (n,)] = rich_string
n += 3

wb.save(tmp_file.name)
`
I get an exception AttributeError 'TextBlock' object has no attribute 'name'
