…ple sheets ### What problem does this PR solve? discussed in https://github.com/infiniflow/ragflow/pull/4102 - In excel_parser.py, `total` means the total number of rows in Excel, but it return in the first iterate, that lead to the wrong `to_page` - In table.py, it when Excel file has multiple sheets, it will be divided into multiple parts, every part size is 3000, `data` may be empty, because it has recorded in the last iterate. ### Type of change - [x] Bug Fix (non-breaking change which fixes an issue)
