Why traverse the DOM when there are ready-to-use collections?
getRowCells: function(tableElement, rowIndex) {
return tableElement.rows[rowIndex].cells;
}

getColumnCells: function(tableElement, columnIndex) {
var rows = tableElement.rows;
var cells = [];
for (var i=0, len=rows.length; i<len; i++) {
cells.push(rows[i].cells[columnIndex]);
}
return cells;
}
Incidentally, tableSection elements have a rows collection too, so
tableElement may not be the best choice of variable name.
