Sets this column's preferred width to preferredWidth.

Usage

From source file:Main.java

/**
 * Pack specified column. Sets the preferred width of the specified visible
 * column so it is will be just wide enough to show the column head and the
 * widest cell value in the column + {@code margin} each side.
 * //from   www  .j  a v  a 2s  .  c o  m
 * Taken from http://www.exampledepot.com/egs/javax.swing.table/PackCol.html
 * 
 * NB: If a table has more than 100 rows, then only the width of the column
 * header will be checked and not the widest cell value. Otherwise it could
 * take too long.
 * 
 * @param table
 *            table with column to pack
 * @param vColIndex
 *            column to pack
 * @param margin
 *            margin to leave at each side of the column (resulting in an
 *            additional width of 2*margin pixels).
