Thank you for the answer.

In this example, the number of rows are predefined and you already know the content of the columns. Is there a way to provide a list of which you do not know in advance how many records it will contain? And where you can easily fill all rows with the correct data?

Hello Ronny,

This was just an example.

It all depends on you. Fell free to experiment and modify the example as you want. It really depends on the context of the application. Where the data is persisted. Does this data comes from a http request.

The simplest modification I can think of, is to pass a reference to the createTableWorkbook(data) to your data and create a workbook by going through it.

Our goal is to show how you could achieve something and then it is your responsibility to adapt it in your application scenario.

Hello Ronny,

This is great! 

If you have further questions, please do not hesitate to contact us again.

I found an other solution for my problem. It works now

I have an array that I fill with data from a list in my view (MVC):

var List = [ ];

@foreach (var l in Model.LabortimeReports.AsQueryable())
{
<text>
List.push({
LAST_DATE: "@l.LAST_DATE",
GTC_DESCRIPTION: "@l.GTC_DESCRIPTION",
ITEM: "@l.ITEM",
REVISION: "@l.REVISION",
PRODUCTCODE: "@l.PRODUCTCODE",
ITEM_DESCRIPTION: "@l.ITEM_DESCRIPTION",
REF: "@l.REF",
NAME: "@l.NAME",
OK: "@(l.OK != null ? decimal.Round((decimal) l.OK) : 0)",
NOK: "@(l.NOK != null ? decimal.Round((decimal) l.NOK) : 0)",
DESC_: "@l.DESC_",
WC_LOC: "@l.WC_LOC",
ANALYST: "@l.ANALYST"
});
</text>
}

I have adjusted the funtion to this:

function createTableWorkbook(data, date) {
var workbook = new $.ig.excel.Workbook($.ig.excel.WorkbookFormat.excel2007);
var sheet = workbook.worksheets().add('bookreport1');
sheet.columns(0).setWidth(72, $.ig.excel.WorksheetColumnWidthUnit.pixel);
sheet.columns(1).setWidth(275, $.ig.excel.WorksheetColumnWidthUnit.pixel);
sheet.columns(2).setWidth(110, $.ig.excel.WorksheetColumnWidthUnit.pixel);
sheet.columns(3).setWidth(275, $.ig.excel.WorksheetColumnWidthUnit.pixel);
sheet.columns(4).setWidth(275, $.ig.excel.WorksheetColumnWidthUnit.pixel);
sheet.columns(5).setWidth(275, $.ig.excel.WorksheetColumnWidthUnit.pixel);
sheet.columns(6).setWidth(275, $.ig.excel.WorksheetColumnWidthUnit.pixel);
sheet.columns(7).setWidth(275, $.ig.excel.WorksheetColumnWidthUnit.pixel);
sheet.columns(8).setWidth(275, $.ig.excel.WorksheetColumnWidthUnit.pixel);
sheet.columns(9).setWidth(275, $.ig.excel.WorksheetColumnWidthUnit.pixel);
sheet.columns(10).setWidth(275, $.ig.excel.WorksheetColumnWidthUnit.pixel);
sheet.columns(11).setWidth(275, $.ig.excel.WorksheetColumnWidthUnit.pixel);
sheet.columns(12).setWidth(275, $.ig.excel.WorksheetColumnWidthUnit.pixel);

// Create a to-do list table with columns for tasks and their priorities.
sheet.getCell('A1').value('LAST DATE');
sheet.getCell('B1').value('PROJECT');
sheet.getCell('C1').value('ITEM');
sheet.getCell('D1').value('REVISION');
sheet.getCell('E1').value('CODE');
sheet.getCell('F1').value('DESCRIPTION');
sheet.getCell('G1').value('WO');
sheet.getCell('H1').value('NAME');
sheet.getCell('I1').value('OK');
sheet.getCell('J1').value('NOK');
sheet.getCell('K1').value('REASON');
sheet.getCell('L1').value('WC');
sheet.getCell('M1').value('ANALYST');

var count = data.length;
var table = sheet.tables().add('A1:M'+count, true);

// Specify the style to use in the table (this can also be specified as an optional 3rd argument to the 'add' call above).
table.style(workbook.standardTableStyles('TableStyleMedium2'));

// Populate the table with data
var row = 2;
for (var i = 0; i < count; i++) {
sheet.getCell('A' + row).value(data[i].LAST_DATE);
sheet.getCell('B' + row).value(data[i].PROJECT);
sheet.getCell('C' + row).value(data[i].ITEM);
sheet.getCell('D' + row).value(data[i].REVISION);
sheet.getCell('E' + row).value(data[i].CODE);
sheet.getCell('F' + row).value(data[i].DESCRIPTION);
sheet.getCell('G' + row).value(data[i].WO);
sheet.getCell('H' + row).value(data[i].NAME);
sheet.getCell('I' + row).value(data[i].OK);
sheet.getCell('J' + row).value(data[i].NOK);
sheet.getCell('K' + row).value(data[i].REASON);
sheet.getCell('L' + row).value(data[i].WC);
sheet.getCell('M' + row).value(data[i].ANALYST);
row++;
}
// Sort the table
table.columns('LAST DATE').sortCondition(new $.ig.excel.OrderedSortCondition());

// Save the workbook
saveWorkbook(workbook, "BookReport_" + date + ".xlsx");
}

I call this function:

createTableWorkbook(List, "@date");

The date that I pass here is a string, defined in my view.

It does not work, even after adding all the same cdns.

I get an error on this line: var workbook = new $.ig.excel.Workbook($.ig.excel.WorkbookFormat.excel2007);

I don't see what I'm doing wrong?
