我正在尝试通过访问带有故障表的JSON文件来添加表。执行此代码时，出现键盘错误。
如果hasattr（result.table，'key_column'）： KeyError：“ key_column”
没有key_column属性。但是为什么代码会进入if条件呢？
with open(report_file_name, 'r') as json_file:
data = json.load(json_file, object_hook=AttributeDictionary)
failure_table_name = add_table(table_style, args.test_id, results_directory, data.failure_table)
def add_table(table_style, test_id, results_directory, result):
if hasattr(result.table, 'key_column'):
result.table.data = sorted(result.table.data, key=lambda x: x[result.table.key_column])
doc = dominate.document(title=result.name)
doc.body.add(style(table_style, type='text/css'))
doc.body.add(p(result.title, _class='table_title'))
result_table = doc.body.add(table(_class='report_table'))
table_body = result_table.add(tbody())
table_row = table_body.add(tr())
for entry in result.table.header:
table_row.add(th(entry))
for row, table_class in zip(result.table.data, get_table_class_iter()):
table_row = table_body.add(tr())
for entry in row:
table_row.add(td(entry, _class=table_class))
file_name = "%s_%s.htm" % (test_id, result.name)
file_path = os.path.join(results_directory, file_name)
with open(file_path, 'w') as html_file:
html_file.write(str(doc))
return file_name
