String representation of a Double value equal to or greater than 0.0 but smaller than Double.PositiveInfinity. An unqualified value is measured in device independent pixels. Strings need not explicitly include decimal points.
A double value as described above (excepting Auto), followed by one of the following unit specifiers: px, in, cm, pt.
px (default) is device-independent units (1/96th inch per unit)
in is inches; 1in==96px
cm is centimeters; 1cm==(96/2.54) px
pt is points; 1pt==(96/72) px
Causes the effective spacing between columns to be set to the current value of the LineHeight property. Equivalent to a property value of NaN.
Type: System.Double The column gap, in device independent pixels. A value of Double.NaN (equivalent to an attribute value of "Auto") indicates that the column gap is equal to the LineHeight property. The default is Double.NaN.
