下文我們一起來看一篇關於Swift多列表格組件的基本功能的例子，希望這篇教程能夠幫助到各位同學，有興趣的朋友可以進來看看哦，具體如下文所示。 與桌面、Web應用不同，受限於屏幕尺寸，移動APP常常采用單列表格來顯示列表數據。但有時我們需要使用多列表格來展示數據（比如：報表數據顯示，或iPad這種大屏設備上展示多欄數據），這些通過網格（UICollectionView）的自定義布局功能就可以實現。   1，多列表格（multi-column table control）效果圖 2，功能說明： （1）表格列頭的標題文字加粗，內容區域的文字正常 （2）表格邊框為1像素黑色邊框 （3）第一列文字居左，其余列文字居中顯示（居左的文字離左側還是有5個像素距離） （4）每列單元格寬度不是平均分配的。而是從右往左，根據表頭文字計算當前列的寬度。剩下的空間就都分配給第一列。 （5）整個組件內部設置了 contentInset，給左右兩側各設置了10像素的距離。這樣組件外部設置100%寬時，左右邊框也不會頂到屏幕邊緣。同時如果有滾動條的時候，滾動條也不會蓋在表格內容區域上方。 （6）點擊單元格控制台會打印出對應的坐標位置。   3，關於collection view重新計算布局時機 （1）shouldInvalidateLayoutForBoundsChange() 方法返回 true，表示當 collection view 的 bounds 改變時，就要重新計算布局。
（2）除了collection view 改變尺寸大小時 bounds 會改變， scroll view 的 bounds 在滾動時也會改變。
（3）本例中，collection view 在滾動的情況下沒必要計算更新布局，否則拖動滾動條的時候布局會不斷地丟棄重新計算，影響性能。  （4）這裡在 shouldInvalidateLayoutForBoundsChange() 中做判斷，只有 collection view 寬度變化時才返回true重新計算布局，否則返回false。   4，項目代碼 --- UICollectionGridViewController.swift（組件類） ---
