说明：  C# Splitter窗口分栏控件，有的说是分割窗体用的，就这么个意思吧，把窗体可分为多个不同结构的部分，可以是上、下结构，也可以是左、右结构，或者是更复杂的结构，这个窗体分栏不属于超级强大型，但以实用为主，新手也能轻松上手。
(C# Splitter Window column controls, some say that split form used on such a meaning of it, the form can be divided into several different parts of the structure may be the upper and lower structure, it can be left and right structure , or more complex structures, this form does not belong to the super powerful column type, but be practical, a novice can easily get started.)
