想在WORD里面分列插入代码，于是就写了这个工具，通过迭代把文字分成等高的N列（因为考虑到字符不等宽，没法计算如何分割）。但是，等我写完这玩意之后，突然想起来css里面有个属性就是column，我捏麻QAQ！！！
I wanna insert code in WORD column by column, so I wrote this tool to divide text into N columns of equal height. However, after I finished this work, it occurred to me that there's a column module in CSS.
Damn it :(

附带一个JS书签，用来跳转到runoob对高亮代码分列。

javascript: (function(){
    if (window.location.host != "c.runoob.com"){
        window.location.href="https://c.runoob.com/front-end/5536/";
    }else{
        var sp = prompt("columns:");
        $("#format_code pre").css({"column-count":sp, "white-space":"pre-wrap", "word-break":"break-all"})
    }
})();
