You can make use of map while iterating table and store VAT in a map and sum up all values to use it later. 您可以在迭代表格时使用地图，并将VAT存储在地图中，然后汇总所有值以供以后使用。 See below code 见下面的代码
NOTE - I did not understand the table structure you followed as I can see lots of <table> tags starting / ending. 注意 -我不了解您遵循的表结构，因为我可以看到很多<table>标记的开始/结束。 Please make sure you have proper html table structure. 请确保您具有正确的html表结构。
//define map here
var map = new Object();
txtPrint += '<hr width=\"100%\" align=left><table width=\"100%\" cellpadding=2 cellspacing=0><tr>';
txtPrint += '<th width=150px align=center><b> Code</b></th>';
txtPrint += '<th width=50px align=center><b>Barcode</b></th>';
txtPrint += '<th width=\"80%\" align=left><b>Material Description</b></th>';
txtPrint += '<th width=\"10%\" align=center><b>Unit Price</b></th>';
txtPrint += '<th width=\"10%\" align=center><b>VAT(%)</b></th>';
txtPrint += '<th width=\"10%\" align=center><b>Quantity</b></th>';
txtPrint += '<th width=\"10%\" align=center><b>Price</b></th>';
txtPrint += '<th width=\"10%\" align=center><b>VAT Amount</b></th>';
txtPrint += '<th width=\"10%\" align=center><b>Total Price</b></th></tr>';
txtPrint += '<table><table><hr width=\"100%\" align=left>';
$.each(invoiceData, function (i, item) {
var ProductName = GetProductName(item.ProductID);
var UnitPrice = item.UnitPrice;
var ProductCode = item.ProductCode;
var VAT = item.VAT;
var Quantity = item.Quantity; // item.QuantityRequested;
var PriceWithVAT = item.UnitPrice;
var VATAmount = CalcVATAmount(UnitPrice, VAT);
var TotalPrice = item.Total;
var Barcode = GenerateBarcodeImg(ProductCode);
txtPrint += '<table width=\"100%\"><tr><td width=\"10%\" align=left>' + ProductCode + '</td>';
txtPrint += '<td width=\"10%\" align=center>' + imgContent + '</td>';
txtPrint += '<td width=\"40%\" align=center>' + ProductName + '</td>';

txtPrint += '<td width=\"10%\" align=center>' + VATAmount + '</td>';
txtPrint += '<td width=\"10%\" align=center>' + TotalPrice + '</td></tr></table>';
//add VAT to map
var vatTotalAmount = parseInt(map.get(VAT)) || 0;
vatTotalAmount += parseInt(VATAmount);
map[VAT] = vatTotalAmount;
});
txtPrint += '</table></table><hr width=\"100%\" align=left></table>';
