Export too large table

I am trying to export more than 15,000 lines to excel in html (they are within table ), however it is not exporting, it only opens a blank browser tab. When I put fewer rows, it exports normally.

Follow the javascript:

function fnExcelReport(tabela)
{
var tab_text="<table border='2px'><tr bgcolor='#87AFC6'>";
var textRange; var j=0;
tab = document.getElementById(tabela); // id of table

for(j = 0 ; j < tab.rows.length ; j++) 
{     
    tab_text=tab_text+tab.rows[j].innerHTML+"</tr>";
    //tab_text=tab_text+"</tr>";
}

tab_text=tab_text+"</table>";
tab_text= tab_text.replace(/<A[^>]*>|<\/A>/g, "");
tab_text= tab_text.replace(/<img[^>]*>/gi,""); 
tab_text= tab_text.replace(/<input[^>]*>|<\/input>/gi, "");

var ua = window.navigator.userAgent;
var msie = ua.indexOf("MSIE "); 

if (msie > 0 || !!navigator.userAgent.match(/Trident.*rv\:11\./))
{
    txtArea1.contentDocument.open("txt/html","replace");
    txtArea1.contentDocument.write(tab_text);
    txtArea1.contentDocument.close();
    txtArea1.focus(); 
    sa=txtArea1.contentDocument.execCommand("SaveAs",true,"arquivo.xls");
}  
else                 
    sa = window.open('data:application/vnd.ms-excel,' + encodeURIComponent(tab_text));  

return (sa);}
