Incomplete borders. VisualCell.cs

[ravetroll]

This code is in the file, but is missing the other two sides of the cell

if (format.BorderBottom != null)
            sb.AddStyle("border-bottom", $"{format.BorderBottom.Width}px solid {format.BorderBottom.Color};");
        if (format.BorderRight != null)
            sb.AddStyle("border-right", $"{format.BorderRight.Width}px solid {format.BorderRight.Color};");

Can we add:

if (format.BorderLeft != null)
            sb.AddStyle("border-left", $"{format.BorderLeft.Width}px solid {format.BorderLeft.Color};");
        if (format.BorderTop != null)
            sb.AddStyle("border-top", $"{format.BorderTop.Width}px solid {format.BorderTop.Color};");

Like it is we can only have a bottom and a right border.

I tested in the browser developer adding those styles and it looked good so this will work.
