专栏目标
在vue和element UI联合技术栈的操控下，本专栏提供行之有效的源代码示例和信息点介绍，做到灵活运用。
（1）提供vue2的一些基本操作：安装、引用，模板使用，computed，watch，生命周期(beforeCreate，created,beforeMount，mounted, beforeUpdate，updated, beforeDestroy，destroyed，activated，deactivated，errorCaptured，components，)、 $root , $parent , $children , $slots , $refs , props, $emit , eventbus ,provide / inject, Vue.observable, $listeners, $attrs, $nextTick , v-for, v-if, v-else,v-else-if，v-on，v-pre，v-cloak，v-once，v-model， v-html, v-text, keep-alive，slot-scope， filters, v-bind，.stop, .native, directives，mixin，render，国际化，Vue Router等
（2）提供element UI的经典操作：安装，引用，国际化，el-row，el-col，el-button，el-link，el-radio，el-checkbox ，el-input，el-select, el-cascader, el-input-number, el-switch,el-slider, el-time-picker, el-date-picker, el-upload, el-rate, el-color-picker, el-transfer, el-form, el-table, el-tree, el-pagination,el-badge,el-avatar,el-skeleton, el-empty, el-descriptions, el-result, el-statistic, el-alert, v-loading, $message, $alert, $prompt, $confirm , $notify, el-breadcrumb, el-page-header,el-tabs ,el-dropdown,el-steps,el-dialog, el-tooltip, el-popover, el-popconfirm, el-card, el-carousel, el-collapse, el-timeline, el-divider, el-calendar, el-image, el-backtop，v-infinite-scroll， el-drawer等
