Get rowIndex = -1 in Chrome. In IE, FF works fine - google-chrome

Question

I would like for first row and column of cells to be assigned a letter and a digit (like an excel table), with rows (cell.cellIndex == 0), no problems it's working fine, but for every column (row.rowIndex == 0 && cell.cellIndex != 0) it works only in browsers IE and FF, in Chrome it's not working. It gets a rowIndex = -1
for (var i = 0; i <= inpRow.value; i++) {
array[i] = new Array();
arrayFunc[i] = new Array();
row = document.createElement('tr')
table.appendChild(row);
for (var j = 0; j <= inpCol.value; j++) {
cell = document.createElement('td');
row.appendChild(cell);
cell.setAttribute('id', (i) + "." + (j));
if (row.rowIndex == 0 && cell.cellIndex != 0) { // row.rowIndex in chrome gets -1
if ((j-1) >= 26) { // j-1 to asign letter from the second cell
var tmp = (j-1) / 26;
for (var f = 0; f < parseInt(tmp, 10) ; f++) {
for (var k = 0; k <= (j-1) - (26 * parseInt(tmp, 10)) ; k++) {
cell.innerHTML = '<b>' + String.fromCharCode(f + 65) + String.fromCharCode(k + 65) + '</b>';
}
}
} else {
cell.innerHTML = '<b>' + String.fromCharCode(j + 64) + '</b>';
}
cell.style.backgroundColor = 'gray';
} else if (cell.cellIndex == 0) {
cell.innerHTML = '<b>' + i + '</b>';
cell.style.backgroundColor = 'gray';
}
}
I have alternative variant using not row and cell Index, but using id:
cell.id.substr(0, 1) == '0' && cell.id != '0.0'
and it works fine in all browsers, but i would like to use cell and row Index:
row.rowIndex == 0 && cell.cellIndex != 0

Answer 1

It seems like both Chrome and Safari assign a row index of -1 to each row you append to a table using the "document.createElement('tr');" approach. Then there is no point searching for or comparing rows by index since each row is simply -1.
Instead of the following 2 lines just before the start of you 2nd for loop:
row = document.createElement('tr')
table.appendChild(row);
use:
row = table.insertRow(-1);
This should do exactly the same job, but Chrome and Safari will now insert correct indexes for each row.

It was a bug in the Webkit layout engine, (that moved to the forked Blink engine as well). This is why it works well in Firefox but not in Chrome (Blink) or Safari (Webkit).
The bug is reported here.
