没有源工作簿的表格，也需要可用的单元格
Recover a table's visible cell contents when all you have is an image. The review grid lets you correct the detected structure before export, which is especially useful for borderless columns and headings spanning more than one field.
Published reference tables
Prepare an editable copy of a report table for your own calculations while retaining the original source and unit labels.
Tables without drawn gridlines
Check whether whitespace-aligned values have landed in the right columns before using them as spreadsheet data.
Rebuild the table structure before using its numbers
- 裁剪至一张表格，并保留解读数值所需的标题或单位。
- 将检测到的列和行与图片进行对比，修正缺失或多出的网格内容。
- 导出已审核的单元格，并在 Excel 中还原所有演示文稿专用格式。
Borderless columns, merged headers and missing rows
- 表格图片需要显示网格线，才能提取到 Excel 吗？
- 清晰的对齐方式也可能表示分栏。无边框布局需要更仔细地检查，因为换行文字和不均匀的间距可能会使检测到的边界发生偏移。
- Will merged headings remain merged in Excel?
- 不要依赖完全准确的版式还原。请检查提取出的表头，并在 Excel 中根据表格含义合并或拆分单元格。
- What if a table image contains footnotes?
- Keep footnotes available as context, but remove any that enter the data grid as false rows. Preserve their meaning in a separate note when needed.
- 导出 XLSX 前，如何修复缺失的行？
- Use the editable review grid to add or correct rows, then compare the row count with the image before downloading the workbook.
