实现部分

1、依赖

<!-- MD to html 工具 -->
<dependency>
<groupId>org.pegdown</groupId>
<artifactId>pegdown</artifactId>
<version>1.6.0</version>
</dependency>
<!-- 引入模板引擎 -->
<dependency>
<groupId>org.apache.velocity</groupId>
<artifactId>velocity</artifactId>
<version>1.7</version>
</dependency>

2、css 添加

<style type="text/css">	html, body, div, span, object, iframe,	h1, h2, h3, h4, h5, h6, p, blockquote, pre,	abbr, address, cite, code,	del, dfn, em, img, ins, kbd, q, samp,	small, strong, sub, sup, var,	b, i,	dl, dt, dd, ol, ul, li,	fieldset, form, label, legend,	table, caption, tbody, tfoot, thead, tr, th, td {		margin:0;		padding:0;		border:0;		outline:0;		font-size:100%;		vertical-align:baseline;		background:transparent;	}		body {		margin:0;		padding:0;		font:12px/15px "Helvetica Neue",Arial, Helvetica, sans-serif;		color: #555;		background:#f5f5f5 url(bg.jpg);	}		a {color:#666;}		#content {width:65%; max-width:690px; margin:6% auto 0;}		/*	Pretty Table Styling	CSS Tricks also has a nice writeup: http://css-tricks.com/feature-table-design/ */		table {		overflow:hidden;		border:1px solid #d3d3d3;		background:#fefefe;		width:70%;		margin:5% auto 0;		-moz-border-radius:5px; /* FF1+ */		-webkit-border-radius:5px; /* Saf3-4 */		border-radius:5px;		-moz-box-shadow: 0 0 4px rgba(0, 0, 0, 0.2);		-webkit-box-shadow: 0 0 4px rgba(0, 0, 0, 0.2);	}		th, td {padding:18px 28px 18px; text-align:center; }		th {padding-top:22px; text-shadow: 1px 1px 1px #fff; background:#e8eaeb;}		td {border-top:1px solid #e0e0e0; border-right:1px solid #e0e0e0;}		tr.odd-row td {background:#f6f6f6;}		td.first, th.first {text-align:left}		td.last {border-right:none;}		/*	Background gradients are completely unnecessary but a neat effect.	*/		td {		background: -moz-linear-gradient(100% 25% 90deg, #fefefe, #f9f9f9);		background: -webkit-gradient(linear, 0% 0%, 0% 25%, from(#f9f9f9), to(#fefefe));	}		tr.odd-row td {		background: -moz-linear-gradient(100% 25% 90deg, #f6f6f6, #f1f1f1);		background: -webkit-gradient(linear, 0% 0%, 0% 25%, from(#f1f1f1), to(#f6f6f6));	}		th {		background: -moz-linear-gradient(100% 20% 90deg, #e8eaeb, #ededed);		background: -webkit-gradient(linear, 0% 0%, 0% 20%, from(#ededed), to(#e8eaeb));	}		/*	I know this is annoying, but we need additional styling so webkit will recognize rounded corners on background elements.	Nice write up of this issue: http://www.onenaught.com/posts/266/css-inner-elements-breaking-border-radius 	And, since we've applied the background colors to td/th element because of IE, Gecko browsers also need it.	*/		tr:first-child th.first {		-moz-border-radius-topleft:5px;		-webkit-border-top-left-radius:5px; /* Saf3-4 */	}		tr:first-child th.last {		-moz-border-radius-topright:5px;		-webkit-border-top-right-radius:5px; /* Saf3-4 */	}		tr:last-child td.first {		-moz-border-radius-bottomleft:5px;		-webkit-border-bottom-left-radius:5px; /* Saf3-4 */	}		tr:last-child td.last {		-moz-border-radius-bottomright:5px;		-webkit-border-bottom-right-radius:5px; /* Saf3-4 */	}</style>

3、遇到的坑

velocity ## 功能与MD 冲突 临时解决办法

context.put("sharp", "##");
vm =vm.replaceAll("##", "\\$sharp");
String email =VelocityUtil.generate(context,vm );

总结：此种方法适合后端程序员使用 省去了样式配置等工作

出来的结果是可以接受的表格也可以。如果有好的方式请告知我 省去的的烦恼
