One way would be to give a class to the table after creating it using setAttribute

var table = document.createElement('table');
table.setAttribute("class", "border_class");

and in your CSS add the border styles

.border_class {
  border: 1px solid blue;
}

So whenever it gets the class(.border_class), the styles are automatically applied

var table = document.createElement('table');
table.setAttribute("class", "border_class");
for (var i = 1; i < 4; i++){
    var tr = document.createElement('tr');   

    var td1 = document.createElement('td');
    var td2 = document.createElement('td');

    var text1 = document.createTextNode('Text1');
    var text2 = document.createTextNode('Text2');

    td1.appendChild(text1);
    td2.appendChild(text2);
    tr.appendChild(td1);
    tr.appendChild(td2);

    table.appendChild(tr);
}
document.body.appendChild(table);

.border_class {
  border: 1px solid blue;
}

You can use classList property to add() CSS classes.

 table.classList.add('myTable')

var table = document.createElement('table');
table.classList.add('myTable')
for (var i = 1; i < 4; i++) {
  var tr = document.createElement('tr');

  var td1 = document.createElement('td');
  var td2 = document.createElement('td');

  var text1 = document.createTextNode('Text1');
  var text2 = document.createTextNode('Text2');

  td1.appendChild(text1);
  td2.appendChild(text2);
  tr.appendChild(td1);
  tr.appendChild(td2);

  table.appendChild(tr);
}
document.body.appendChild(table);

.myTable {
  border: 1px solid green;
}

You can define border in a class and add class to your table with table.className.

var table = document.createElement('table');
for (var i = 1; i < 4; i++){
    var tr = document.createElement('tr');   

    var td1 = document.createElement('td');
    var td2 = document.createElement('td');

    var text1 = document.createTextNode('Text1');
    var text2 = document.createTextNode('Text2');

    td1.appendChild(text1);
    td2.appendChild(text2);
    tr.appendChild(td1);
    tr.appendChild(td2);

    table.appendChild(tr);
}
table.className="tbl";
document.body.appendChild(table);

.tbl{
  border:2px solid #000000;
}

On the other hand you can just style all the table elements or give id to table element and write specific styles to it.

var table = document.createElement('table');
for (var i = 1; i < 4; i++){
    var tr = document.createElement('tr');   

    var td1 = document.createElement('td');
    var td2 = document.createElement('td');

    var text1 = document.createTextNode('Text1');
    var text2 = document.createTextNode('Text2');

    td1.appendChild(text1);
    td2.appendChild(text2);
    tr.appendChild(td1);
    tr.appendChild(td2);

    table.appendChild(tr);
}
table.id="tblBordered";
document.body.appendChild(table);

table#tblBordered{
  border:2px solid #000000;
}

You can use table.style.border = "thick solid #0000FF";

var table = document.createElement('table');
for (var i = 1; i < 4; i++) {
    var tr = document.createElement('tr');

    var td1 = document.createElement('td');
    var td2 = document.createElement('td');

    var text1 = document.createTextNode('Text1');
    var text2 = document.createTextNode('Text2');

    td1.appendChild(text1);
    td2.appendChild(text2);
    tr.appendChild(td1);
    tr.appendChild(td2);

    table.appendChild(tr);
}
table.style.border = "thick solid #0000FF";
document.body.appendChild(table);

You can do it in two ways.

1.) By using style attribute which is attached to the DOM object.

var table = document.createElement('table');    
table.style.border = '1px solid black';

2.) By using setAttribute() method.

var table = document.createElement('table');
table.setAttribute("class", "tbl-border");

And add the border styles in your CSS file.

.tbl-border {
  border: 1px solid black;
}

NB: The preferred way to add styles in your element is the second one, using the setAttribute() method.
