如何给BootstrapTable静态赋值

今天要做一个报表导入并预览的功能，使用layui的文件上传，获取表格数据，接着把表格数据返回前台，使用bootstraptable展示，实现一个预览表格数据的效果。

通过后台处理后的数据

// 数据经过处理后,真实数据已做修改
Data = [
	{JJSRBY: 6666,JJSRBYLJ: 155666,JJZCBY: 777,JJZCBYLJ: 2266633,LJJY: 151515,NCYE: 121212,SZYEBY: 11111,SZYEBYLJ: -11559,XZ: "企业职工基本养老保险",ZFNL: 22.1},
	{JJSRBY: 6666,JJSRBYLJ: 155666,JJZCBY: 777,JJZCBYLJ: 2266633,LJJY: 151515,NCYE: 121212,SZYEBY: 11111,SZYEBYLJ: -11559,XZ: "工伤保险",ZFNL: 22.1},
	...
];

bootstraptable加载数据

// field 需要和 Data中每个对象中的字段名对应。
// 
$('#previewTable').bootstrapTable({
	    data : Data,
	    //toolbar: '#toolBar', 
	    striped: true, //是否显示行间隔色
	    cache: false, //是否使用缓存，默认为true，
	    //minimumCountColumns: 2, //最少允许的列数
	    clickToSelect: true, //是否启用点击选中行
	    columns: [
	   		[
	   	      {field : 'XZ', title: '险种', rowspan:2, align:"center"},
	   	      {field : 'NCYE', title: '年初余额', rowspan:2,halign:"center",align:"right",
	   	    	formatter: function(value, row, index) {
	   	    		let num = row.NCYE;
	  				return num.toFixed(2);

	    formatNoMatches : function() {
