行。它归结为这3行。
"th" => "<pre><th class=\"row%number%\" style=\"%type%\">%text%</th></pre>",
"td" => "<pre><td class=\"col%number%\" style=\"%type%\">%text%</td></pre>",
"tr" => "<pre><tr class=\"row%number%\" style=\"%type%\">%text%</tr>\</pre>n",
任何wiki wiki的人都知道如何将其变成样式文本吗？
答案 0 :(得分：0)
"td" => "<td class=\"col%number%\" style=\"%type%\"><code>%text%</code></td>",
我添加了标签。中提琴。
