1、字体颜色设置，最简单的办法

   style:'color: #f6d06'

,{field: 'rongQiJiHuaCha',title: '容器',align:'center', width:'60',style:'color: #f67d06;', totalRow: true}

2、给列设置背景色

 
  done: function (res, curr, count) {
           var that = this.elem.next();
           res.data.forEach(function (item, index) {
            // 所需的条件
              if(item.shouldMonth > 0){
            // 添加颜色--#1E9FFF ；'threeMonth'根据需要填充背景色的field进行更改
                that.find(".layui-table-box tbody tr[data-index='" + index + "'] td[data-field='threeMonth']").css("background-color", "#1E9FFF");
            }
           });}
