Below is my implementation...

I asked the question here as well, but after a few minutes I reaslized, it is extremly easy

// Return all the values of a row, based on the current cell row id
function getRowArray(row){
var aantal_kolommen = obj.getColumnCount();
RowArray = new Array();
for (k=0 ; k < aantal_kolommen ; k++ ) {
RowArray[k] = obj.getCellText(k ,row);
}
return RowArray;
}
