If you want to redraw the whole row, you can use:

celltable.redrawRow(absIndex);

But if you want to update a single cell and performance is important you could do this in a child class of CellTable

public void updateCellContent(int absRowIndex, int cellIndex, String innerHtml) {
    TableRowElement tr = getChildElement(absRowIndex);
    if (tr != null) {
        TableCellElement td = tr.getCells().getItem(cellIndex);
        if (td != null) {
            td.setInnerHTML(innerHtml);
        }
    }
}

Take a look at https://stackoverflow.com/a/7109021/787660

When you use the ListDataAdapter and add your row like in the example using the ListWrapper (don't be scared, you use it like a List-Object) the refresh is automatically triggered.

I suppose you use a ListDataProvider to store as it is used in the showcase example here.

In that case you just have to up change the data in the ListDataProvider and when its done just call

cellTable.redraw();

And don't worry the table doesn't flicker when doing that :)
