vue前端自适应布局，一步到位所有自适应

页面展示

在这里插入图片描述

实现内容

1，左右布局

左侧固定宽带，右侧自适应剩余的宽度。
中间一条分割线，可以拖拉，自适应调整左右侧的宽度。
左侧的高度超长自动出现横向滚动条，左侧宽度超长，自动出现竖向滚动条。

2，上中下布局

最上面的搜索条件 div 固定占用 100 px 高度，下面的查询条件 div 固定占用 30 px 高度，最下面的分页固定占用高度，页面剩下的高度自动分配给中间的表格内容。
表格内容高度超过后自动出现竖向滚动条，宽度超出后自动出现横向滚动条。
点击按钮，可以隐藏/显示搜索条件 div 里面的内容。
当隐藏搜索条件 div 里面的内容时，中间表格的高度为：整个页面的高度—操作按钮div的高度—分页div的高度。
当搜索条件 div 里面的内容时，中间表格的高度为：整个页面的高度—搜索条件div的高度—操作按钮div的高度—分页div的高度。
2，分辨率自适应
加载即动态实时计算高度，宽度
