Title: How to bold the column header in the exported?
Post by: Alfred on March 08, 2017, 11:22:28 PM

I have got this code from this forum: When I use the code in my application. The exported excel does not bold the column header?

Code:

$.extend($.fn.datagrid.methods, {
    toExcel: function(jq, filename){
        return jq.each(function(){
            var uri = 'data:application/vnd.ms-excel;base64,'
            , template = '<html xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:x="urn:schemas-microsoft-com:office:excel" xmlns="http://www.w3.org/TR/REC-html40"><head><!--[if gte mso 9]><xml><x:ExcelWorkbook><x:ExcelWorksheets><x:ExcelWorksheet><x:Name>{worksheet}</x:Name><x:WorksheetOptions><x:DisplayGridlines/></x:WorksheetOptions></x:ExcelWorksheet></x:ExcelWorksheets></x:ExcelWorkbook></xml><![endif]--></head><body><table>{table}</table></body></html>'
            , base64 = function (s) { return window.btoa(unescape(encodeURIComponent(s))) }
            , format = function (s, c) { return s.replace(/{(\w+)}/g, function (m, p) { return c[p]; }) }

            var alink = $('<a style="display:none"></a>').appendTo('body');
            var view = $(this).datagrid('getPanel').find('div.datagrid-view');
            var table = $(this).datagrid('getPanel').find('div.datagrid-view2').clone();
            var tbody = table.find('>tbody');
            view.find('div.datagrid-view1 table.datagrid-btable>tbody>tr').each(function(index){
                $(this).clone().children().prependTo(tbody.children('tr:eq('+index+')'));
            });
            var ctx = { worksheet: name || 'Worksheet', table: table.html()||'' };
            alink[0].href = uri + base64(format(template, ctx));
            alink[0].download = filename;
            alink[0].click();
            alink.remove();
        })
    }
});

Is there any way to append caption tag for the title of the table?

Please use this code instead.

Code:

$.extend($.fn.datagrid.methods, {
    toExcel: function(jq, filename){
        return jq.each(function(){
            var uri = 'data:application/vnd.ms-excel;base64,'
            , template = '<html xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:x="urn:schemas-microsoft-com:office:excel" xmlns="http://www.w3.org/TR/REC-html40"><head><!--[if gte mso 9]><xml><x:ExcelWorkbook><x:ExcelWorksheets><x:ExcelWorksheet><x:Name>{worksheet}</x:Name><x:WorksheetOptions><x:DisplayGridlines/></x:WorksheetOptions></x:ExcelWorksheet></x:ExcelWorksheets></x:ExcelWorkbook></xml><![endif]--></head><body><table>{table}</table></body></html>'
            , base64 = function (s) { return window.btoa(unescape(encodeURIComponent(s))) }
            , format = function (s, c) { return s.replace(/{(\w+)}/g, function (m, p) { return c[p]; }) }

            var alink = $('<a style="display:none"></a>').appendTo('body');
            var view = $(this).datagrid('getPanel').find('div.datagrid-view');
            var table = view.find('div.datagrid-view2 table.datagrid-btable').clone();
            var tbody = table.find('>tbody');
            var thead = $('<thead></thead>').insertBefore(tbody);
            view.find('div.datagrid-view2 table.datagrid-htable>tbody').children().clone().appendTo(thead);
            view.find('div.datagrid-view1 table.datagrid-htable>tbody>tr').children().clone().prependTo(thead.find('tr'));
            view.find('div.datagrid-view1 table.datagrid-btable>tbody>tr').each(function(index){
                $(this).children().clone().prependTo(tbody.children('tr:eq('+index+')'));
            });
            var ctx = { worksheet: name || 'Worksheet', table: table.html()||'' };
            alink[0].href = uri + base64(format(template, ctx));
            alink[0].download = filename;
            alink[0].click();
            alink.remove();
        })
    }
});

Thanks Jerry, But your code does not include the footer: I use below code to solve my problem. I also solved the bold column header now using the strong tag in the table code. One more feature I would like to add is adding the caption of the table with extra parameter in the method like: $('#dg').datagrid('toExcel','Customer.xls','List of Customer');. I am trying something to caption tag using insertBefore, but it always outputs `undefined` when opened in Excel 2013. And It does not merge the column also.

Here is the working code without the caption.

view.find('div.datagrid-view1 table.datagrid-btable>tbody>tr').each(function(index){
$(this).clone().children().prependTo(tbody.children('tr:eq('+index+')'));
});

var ctx = { worksheet: name || 'Worksheet', table: table.html()||'' };
alink[0].href = uri + base64(format(template, ctx));
alink[0].download = filename;
alink[0].click();
alink.remove();
})
}
