Generate HTML table from 2D JavaScript array

Question

In JavaScript, is it possible to generate an HTML table from a 2D array? The syntax for writing HTML tables tends to be very verbose, so I want to generate an HTML table from a 2D JavaScript array, as shown:

[
  ["row 1, cell 1", "row 1, cell 2"], 
  ["row 2, cell 1", "row 2, cell 2"]
]

would become:

<table border="1">
  <tr>
    <td>row 1, cell 1</td>
    <td>row 1, cell 2</td>
  </tr>
  <tr>
    <td>row 2, cell 1</td>
    <td>row 2, cell 2</td>
  </tr>
</table>

So I'm trying to write a JavaScript function that would return a table from a 2D JavaScript array, as shown:

function getTable(array){
  // take a 2D JavaScript string array as input, and return an HTML table.
}

Here's a function that will use the dom instead of string concatenation.

function createTable(tableData) {
  var table = document.createElement('table');
  var tableBody = document.createElement('tbody');

  tableData.forEach(function(rowData) {
    var row = document.createElement('tr');

    rowData.forEach(function(cellData) {
      var cell = document.createElement('td');
      cell.appendChild(document.createTextNode(cellData));
      row.appendChild(cell);
    });

    tableBody.appendChild(row);
  });

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

createTable([["row 1, cell 1", "row 1, cell 2"], ["row 2, cell 1", "row 2, cell 2"]]);
