表頭列頭固定式頁面面，頭列固定式頁面面
該文章主要是寫了一個table頁面,並固定表頭或者列頭,以達到excel凍結列的效果,主要使用的js的scrollTop,scrollLeft.
一.js中scrollTop及scrollLeft的使用說明scrollTop指的是“元素中的內容”超出“元素上邊界”的那部分的高度。例如:外層元素的高度值是200px
,內層元素的高度值是300px
。很明顯，“外層元素中的內容”高過了“外層元素”本身.當向下拖動捲軸時，有部分內容會隱沒在“外層元素的上邊界”之外，scrollTop就等於這部分“不可見的內容”的高度。scrollLeft同上.
二.頁面樣本頁面範例程式碼如下:
