'table.ke-zeroborder td {border:1px dotted #AAA;}',
替换成,防止td内输入数字英文不会换行。
'table.ke-zeroborder td {border:1px dotted #AAA;word-wrap: break-word;word-break: break-all;}',

line:6865

imgPath = self.pluginsPath + name + '/images/',
下面加(定义删除图片的api)：
delImgApi = K.undef(self.delImgApi, 'delurl'),
//配置时记得自定义参数：delImgApi:'https://xxxxxxx'

'<div style="padding:10px 20px;">',
下面加
'<style type="text/css">',
            '.relative{position:relative;}',
            '.operate-box{',

el.click(function(e) {

改成：
$(el).find(".icon-add").click(function(e) {
    clickFn.call(this, fileUrl, data.filename);
});

line:7009

.mouseover(function(e) {
    K(this).addClass('ke-on');

改成
.mouseout(function(e) {
    K(this).removeClass('ke-on');
    //删除图片功能：鼠标移出，让操作框向下滑出
    $(K(this)).find(".operate-box").css({"top":"-100px"});

                }
                photoDiv.append(img);
加个属性data-id
并且在img绑定事件之前 增加删除按钮 
替换成
var img = K('<img src="' + iconUrl + '"  data-id="' + data.id + '" width="80" height="80" alt="' + data.filename + '" />');

                photoDiv.append(img);
                //添加删除图片功能
                var bgHtml = [

                    '</div>'
                ].join(" ");
                photoDiv.append(bgHtml);
                if (!data.is_dir || data.has_file) {
                    photoDiv.css('cursor', 'pointer');

                    photoDiv.attr('title', lang.emptyFolder);
                }
                $(photoDiv).find(".icon-delete").click(function(event){
                    if(!confirm("确认删除该图片吗？")) return false;
                    var parentDiv =  $(this).parents(".ke-item");
                    var id_ = $(this).parents(".ke-photo").find("img:first").attr("data-id");
                    //发送删除图片请求
                    $.post(delImgApi,{imgId: id_},function(json){
                        if(json.error===0) {
                            parentDiv.remove();
                        } else {
                            alert(json.message);
                        }
                    },"json");
                });

最后补充两个icon在路径： \kindeditor\plugins\filemanager\images 自己不喜欢可以替换
