ExtJS先進的流體邊界佈局

Question

我需要爲我們的報告系統創建一個先進的，流暢的邊界佈局。

西面窗格將被拆分成2個獨立的窗格，頂部用於過濾窗體，底部用於導航。

中心窗格將被拆分爲3個獨立的窗格，頂部爲主數據網格，2個底部窗格爲子報表網格。我可能在某個時候需要3個底部窗格，但我希望避免這種情況。

這裏是我所期待的一個例子：http://dl.dropbox.com/u/298258/Amistaff/desiredLayout.png

我到目前爲止肯定是不盡如人意。

下面是代碼：

非常感謝AMOL下面的答案。我還有一個問題。如果我在西部地區摺疊表格，我該如何調整導航面板以填充剩餘空間？
