NatTable (1)

NatTable のサンプルを備忘録として掲載していきます。最初のうちは NatTable のサンプルを転用したものからはじめていきます。いまのところ、人様に対して詳細な解説を加えられるレベルまで理解が追いついていません。ひたすらサンプルを積み重ねて行きます。

Eclipse (LUNA 4.4.0 on CentOS 7) で使用したライブラリは以下の通りです。

今回は、NatTable のサンプル _001_Getting_Started.java と Person.java をベースにしました。

List: NatTableSample001.java
