表格知识库数据查询不准确

1 在智能体中配置表格知识库，表格中有4700条数据
2 通过提问：表格中有多少条数据，只返回了最大召回数量的数据：10条

No files, tests, or entry points are named in the report. Start by reproducing the table knowledge-base query with 4,700 rows and the question about the row count, then trace where the maximum retrieval count of 10 is applied. Done means the agent returns the actual total rather than only the retrieved rows.
