Change Border Line Color

[Nicholas]

I set border for one range of my Excel worksheet. I need to change the border color from black to blue and make the border line be more thicker. Can Spire.Doc support it?

You can select the Range to set directly.
sheet.Range["B3"].Borders.Color = Color.Blue;
sheet.Range["B3"].Borders.LineStyle = LineStyleType.Thin;
