word中表格复制到在线编辑器字体重叠问题解决(javaeye也有此问题)
项目中用了在线编辑器，类似javaeye发布文章的，出现字体重叠现象，(我们项目用的是richtxt),在网络上搜索了几十个在线编辑器，都出现下列问题（网易博客的在线编辑器不出现，但源码找不到）：

通过查看和比较word代码，发现样式表中有一个line-height属性影响了此问题，因为在项目中用的是richtxt，所以在editor.js中修改下面代码可以解决此问题，见红色部分：
?
if(pasteData && pasteData.length > 0) {
??? ??? ??? ??? ??? var wordPattern = /<\w[^>]* class="?MsoNormal"?/gi;
??? ??? ??? ??? ??? if(wordPattern.test(pasteData)) {
??? ??? ??? ??? ??? ??? if(confirm("文章有多余代码，可能影响顺利发表，是否确认清除？\r\n\r\n提示：您的文字将完整保留。")) {
??? ??? ??? ??? ??? ??? ??? pasteData = clearFromWord(pasteData);
??? ??? ??? ??? ??? ??? }
??? ??? ??? ??? ??? ??? else {???
??? ??? ??? ??? ??? ??? ??? pasteData = pasteData.replace(/<img+.[^>]*>/gi, "");
??? ??? ??? ??? ??? ??? ??? pasteData = pasteData.replace(/<\/?\w+:imagedata[^>]*>/gi, "");
??? ??? ??? ??? ??? ??? ??? pasteData = pasteData.replace(/<\/?\w+:shape[^>]*>/gi, "");
??? ??? ??? ??? ??? ??? ?
??? ??? ??? ??? ??? ??? ??? var reg=new RegExp("LINE-HEIGHT:[^s]*\;?","gi");
??? ??? ??? ??? ??? ??? ??? pasteData = pasteData.replace(reg, "");
??? ??? ??? ??? ??? ??? ??
??? ??? ??? ??? ??? ??? }
??? ??? ??? ??? ??? }
??? ??? ??? ??? ??? var oRTE = _this.iframe.contentWindow;
??? ??? ??? ??? ??? var oRng = oRTE.document.selection.createRange();
??? ??? ??? ??? ??? oRng.pasteHTML(pasteData);
??? ??? ??? ??? }
