Style Excel Cell Borders & Fonts
IronXL for Python allows developers to style any Excel Cell or Range. IronXL covers most of the styling available in Microsoft Excel, including fonts, text alignment, borders, colors, backgrounds, and fill patterns. The code example below demonstrates a wide range of styles that can be configured with IronXL.
Individual cell and range borders (bottom, top, left, right, and diagonal) can be set to 14 different border styles—such as dotted, dashed, and double—using the BorderType enum. The ShrinkToFit and WrapText properties provide additional control over how the spreadsheet manages cell content and sizes.
