fastAdmin框架表格内容文字过长，显示部分内容和省略号

{field: 'content', title: __('文件内容'),
    formatter : function(value, row, index, field){
        return "<span style='display: block;overflow: hidden;text-overflow: ellipsis;white-space: nowrap;' title='" + row.content + "'>" + value + "</span>";
    },
    cellStyle : function(value, row, index, field){
        return {
            css: {
                "white-space": "nowrap",
                "text-overflow": "ellipsis",
                "overflow": "hidden",
                "max-width":"150px"
            }
        };
    }},
