'Declaration Public Property Width As Nullable(Of Single)
public Nullable<float> Width {get; set;}
WordprocessingML persists border widths in units equal to one-eighth of a desktop publishing point; this equates to 1/576 of an inch. The range of valid values spans from one-fourth of a point to 12 points.
A value which is based on a specific number of pixels can be assigned using the SetWidthInPixels method.
WordprocessingML supports border thicknesses up to one-sixth of an inch. Values which exceed this amount are not recognized, and the resulting border thickness resolves to this value.
