Additional work over the "jp.gr.java_conf.tame.swing.table" project.
Last edit about 2011, no support provided anymore. Project shared to be an example of library use. All code in "vsubhuman.swing.spantable" and "vsubhuman.xlsmanager" package is distributed under WTFPL - free to use in any way.
Package "vsubhuman.xlsmanager" contains examples of use for the SpanTable lib.
