直接在对应的js中字段中显示：
{field: 'remark', title: __('Remark'), operate: false,formatter : function(value, row, index, field){return "<span style='display: block;overflow: hidden;text-overflow: ellipsis;white-space: nowrap;' title='" + row.remark + "'>" + value + "</span>";},cellStyle : function(value, row, index, field){return {css: {"white-space": "nowrap","text-overflow": "ellipsis","overflow": "hidden","max-width":"150px"}};}
},
