默认ckedtor编辑器会过滤掉word的排版格式，如果你经常要保存word的格式，请按如下修改

用编辑工具打开\editor\plugins\pastefromword\filter\default.js

找到如下代码

if(R){var S=R[1]||Q&&'l.',T=S&&S.match(/>(?:[(]?)([^\s]+?)([.)]?)</);return D(T,S);}if(CKEDITOR.env.gecko&&Q){var U=CKEDITOR.htmlParser.fragment.fromHtml(Q[0]).children[0],V=P.previous,W=V&&V.value.match(/<v:imagedata[^>]*o:href=['"](.*?)['"]/),X=W&&W[1];X&&(U.attributes.src=X);return U;}return false;}:z};}},t=function(){this.dataFilter=new CKEDITOR.htmlParser.filter();};t.prototype={toHtml:function(u){var v=CKEDITOR.htmlParser.fragment.fromHtml(u,false),w=new CKEDITOR.htmlParser.basicWriter();v.writeHtml(w,this.dataFilter);return w.getHtml(true);}};CKEDITOR.cleanWord=function(u,v){return u;if(CKEDITOR.env.gecko)u=u.replace(/(<!--\[if[^<]*?\])-->([\S\s]*?)<!--(\[endif\]-->)/gi,'$1$2$3');var w=new t(),x=w.dataFilter;x.addRules(CKEDITOR.plugins.pastefromword.getRules(v));v.fire('beforeCleanWord',{filter:x});try{u=w.toHtml(u,false);}catch(y){alert(v.lang.pastefromword.error);}u=u.replace(/cke:.*?".*?"/g,'');u=u.replace(/style=""/g,'');u=u.replace(/<span>/g,'');return u;};})();

增加上面红色的return u;即可。
