使用RichTextCellType可以显示平方或者立方等指数形式的数据。代码如下:

  1. RichTextEditor editor = new RichTextEditor();
    
                editor.Text = "3";
    
                editor.SelectionCharOffset = -10;
    
                editor.SelectedText = "2";
    
    
    
                RichTextCellType type = new RichTextCellType();
    
                
    
                this.fpSpread1.ActiveSheet.Cells[1, 1].CellType = type;
    
                this.fpSpread1.ActiveSheet.Cells[1, 1].Value = editor.Rtf;复制代码

效果如下:
