Return nxn array of Data from Handsontable using .getSourceData

Question

I am attempting to get the source data object from a "handsontable" using .getSourceData method. The console logs an array of arrays if I call the method using no optional parameters however when I attempt to pass these parameters I get console errors. I have a Fiddle that works to output array but does not work if I uncomment the optional parameter method.

var data = [
  [0, 0, 0],
  [10, 0.1, 150],
  [20, 0.2, 151]
]

var container1 = document.getElementById('Table'),
  hot1;

var hot1 = new Handsontable(container1, {
  data: data,
  colHeaders: ['Measured Depth', "Inclination", "Azimuth"],
  rowHeaders: true,
  minSpareRows: 0,
  contextMenu: ['row_above', 'row_below', 'remove_row']
});

function countRows() {
  var ht = hot1
  var rowcount = ht.countRows() - ht.countEmptyRows();
  return rowcount;
}

console.log(countRows())

function submitForm() {
  var htContents = hot1.getSourceData() //getSourceData(1,1,countRows(),3)
  console.log(htContents);
}

$("#get_data").click(submitForm);

I never got that function to work however what did work is to use countRows() to limit my output from returning blanks ie

for (i = 0; i < countRows(); i++) {
  md.push(htContents[i][0]);
  inc.push(htContents[i][1]);
  azi.push(htContents[i][2]);
}
