注:因为我这是markdown的编辑器,不支持一键复制保留table的样式,因此,上图的表格,是从原文中摘录下来的。因为表格内容太多,所以绝对不可能通过一行一行的copy,重复工作太多。因此,博主写了一段简单的js,实现一键copy文中的表格内容为markdown格式的文本。代码如下:

$("table").find("tbody tr").each(function () {
    var $this = $(this);
    var html = '| ' + $this.find("td:eq(0) p").html() + '     |     ' + $this.find("td:eq(1)  p").html() + '     | ' + $this.find("td:eq(2)  p").html() + '    |';
    console.log(html);
});

最后将生成的markdown格式的文本内容copy到编辑器中即可。(简单!暴力!)
