is the column width setting. Column width can be specified as a proportional
measure, a fixed measure, or a mixed measure.
- A proportional measure is of the
form "number*" (eg, "10*"), and means that the column width is the number times the
proportion.
- A fixed measure is of the form number and unit (eg, "25pt", "25mm",
"16.2in"). The units are case insensitive and can be "pt" (points), "cm" (centimeters),
"mm" (millimeters), "pi" (picas), and "in" (inches). The default fixed unit must be
"pt"
if neither a proportion nor a fixed unit is specified. An example of a mixed measure
is
"10*"+"3pt".
- If no column width is specified for a column specification, this
implies that the column has the proportional width "1*", and hence, if no column widths
are specified for any column, the column widths will be the same for each column and
will be an equal proportion of the available width.
