Csharp iText 7 单元格文本旋转

这应该可以完成工作，包括文本对齐和防止单词换行

var dateCell = new Cell().SetWidth(UnitValue.CreatePercentValue(1 * 5))
        .SetHeight(UnitValue.CreatePercentValue(30)) // Adjust the cell height as needed
        .SetTextAlignment(TextAlignment.CENTER) // Set text alignment to center
        .SetPaddingBottom(10) // Adjust the bottom padding as needed
        .Add(new Paragraph("3/5/23")).SetFontSize(8);

    // Adjust rotation angle to make it fall slightly to the right
    dateCell.SetRotationAngle(Math.PI / 4);

备注中的替代选项

var paragraph = new Paragraph("3/5/23");

// Adjust rotation angle to make it fall slightly to the right    
paragraph.SetRotationAngle(Math.PI / 4);

var dateCell = new Cell().SetWidth(UnitValue.CreatePercentValue(1 * 5))
        .SetHeight(UnitValue.CreatePercentValue(30)) // Adjust the cell height as needed
        .SetTextAlignment(TextAlignment.CENTER) // Set text alignment to center
        .SetPaddingBottom(10) // Adjust the bottom padding as needed
        .Add(paragraph).SetFontSize(8);
