formula is incorrect when an empty space is included in the column. It can be reproduced in the following ways.
The sum should be three, but it says four.
function getData() {
return [
[1],
[1],
[1],
[],
['=SUM(A1:A4)']
];
}
var example1 = document.getElementById('example1');
var settings1 = {
data: getData(),
rowHeaders: true,
colHeaders: true,
contextMenu: true,
formulas: true
};
var hot1 = new Handsontable(example1, settings1);
hot1.setDataAtCell(0, 0, 2);
hot1.setDataAtCell(1, 0, 2);
hot1.alter('remove_row', 1, 1);
