TSV（Tab分隔值）

Tab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。记录之间由换行符分隔，记录内的值由制表符分隔。

UnstructuredTSVLoader（非结构化TSV加载器）

您还可以使用UnstructuredTSVLoader加载表格。使用UnstructuredTSVLoader的一个优点是，如果在“elements”模式下使用它，表格的HTML表示将在元数据中可用。

from langchain.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"])
