/**
 *  類似HTML 中Table的網格Table
 *          如何用ListView實現自適應的表格。GridView比ListView更容易實現自適應的表格，
 * 但是GridView每個格單元的大小固 定，而ListView實現的表格可以自定義每個格單元的大小，但
 * 因此實現自適應表格也會復雜些(格單元大小不一)。
 *        另外，GridView實現的表格可 以定位在具體某個格單元，而ListView實現的表格則
 * 只能定位在表格行。因此還是那句老話：根據具體的使用環境而選擇GridView 或者 ListView實現表格。
 *
 *          本文實現的ListView表格，可以每個格單元大小不一，文本(TextView)或圖片(ImageView)
 *做格單元的數據，不需要預先定義XML實現樣式(自適應的根本目標)。由于ListView置于
 *HorizontalScrollView中，因此對于列比較多/列數據比較長的數據表也能很好地適應其
 *寬度。
