可能的使用场景
Aspose.Cells允许你使用Shape.textBody.textAlignment属性设置任何形状或评论的边距，该属性返回Aspose.Cells.Drawing.Texts.ShapeTextAlignment类的对象，具有不同的属性（如ShapeTextAlignment.topMarginPt、ShapeTextAlignment.leftMarginPt、ShapeTextAlignment.bottomMarginPt、ShapeTextAlignment.rightMarginPt等）可用于设置上下左右边距。
设置工作表内批注或形状的边距
请参阅以下示例代码。它加载包含两个形状的示例Excel文件。代码逐个访问形状，并设置它们的顶部、左侧、底部和右侧边距。请参阅由代码生成的输出Excel文件以及显示代码对输出Excel文件的影响的屏幕截图。
