周末對ext布局進(jìn)行了研究，發(fā)現(xiàn)以前覺得比較麻煩的東西，現(xiàn)在看來十分簡單。ext的使用不是特別困難，但是如何才可以保證ext可以滿足各種變態(tài)的頁面需求的同時(shí)又可以使開發(fā)人員不去接觸一堆一堆的js呢？這個(gè)問題肯定是個(gè)難題。
還是貼點(diǎn)代碼。下面的代碼實(shí)現(xiàn)了利用table模式布局FormPanel。解決了在非form模式下label不能顯示的問題，但是還是存在問題，例如通常情況下“開始日期”和“結(jié)束日期”一般只占一個(gè)column，也就是兩個(gè)元素各占半個(gè)column。
