在从工作表读取数据时，我们需要知道最大的区域。
在从工作表复制所有数据时，我们需要知道最大的区域。
在将指定区域导出到html和pdf时，我们需要知道最大的区域。
Aspose.Cells for Python via .NET包含查找工作表中最大范围的不同方法。
如何获取最大范围
在Aspose.Cells for Python via .NET中，如果初始化了row和column对象，这些行和列将被计算到最大的区域，即使空行或空列中没有数据。

| from aspose.cells import Workbook | |
| workbook = Workbook("Book1.xlsx") | |
| # Get all the worksheets in the book. | |
| worksheets = workbook.worksheets | |
| sheet = worksheets[0] | |
| # Gets the max data range. | |
| maxRow = sheet.cells.max_row | |
| maxColumn = sheet.cells.max_column | |
| # The range is A1:B3. | |
| range = sheet.cells.create_range(0, 0, maxRow + 1, maxColumn + 1) | |
| sheet.cells.get("A10").put_value(None) | |
| maxRow = sheet.cells.max_row | |
| maxColumn = sheet.cells.max_column | |
| # The range is udpated to A1:B10. | |
| range = sheet.cells.create_range(0, 0, maxRow + 1, maxColumn + 1) |
如何获取最大数据范围
在大多数情况下，我们只需要获取包含所有数据的所有范围，即使范围外的空单元格被格式化。 关于形状、表格和数据透视表的设置将被忽略。

如何获取最大显示范围
当我们将工作表中的所有数据导出到 HTML、PDF 或图像时，需要获取一个包含所有可见对象的区域，包括数据、样式、图形、表格和数据透视表。 以下代码展示了如何将最大显示范围呈现为 HTML:
