制表符分隔值 (TSV) 文件是一种简单的、基于文本的文件格式，用于存储表格数据。[3] 记录由换行符分隔，记录中的值由制表符分隔。
UnstructuredTSVLoader
你也可以使用 UnstructuredTSVLoader 加载表格。使用 UnstructuredTSVLoader 的一个优点是，如果你在 "elements" 模式下使用它，表格的 HTML 表示将可在元数据中获取。
from langchain_community.document_loaders.tsv import UnstructuredTSVLoader
loader = UnstructuredTSVLoader(
file_path="./example_data/mlb_teams_2012.csv", mode="elements"
)
docs = loader.load()
print(docs[0].metadata["text_as_html"])
<table border="1" class="dataframe">
<tbody>
