Re: Grid with <td rowspan="2">

[Manuel Carrasco Moñino]

you can use different ways to create a new table in gwt:

- Uibinder:
<ui:UiBinder xmlns:ui="urn:ui:com.google.gwt.uibinder">
<div>
<table ui:field="mytable">
</table>
</div>
</ui:UiBinder>

@UiField
TableElement mytable;

- HTML
HTML html = new HTML("<table></table>");

- GwtQuery
$(document).append("<table></table>");


But if you want to modify an existing Grid widget with handwritten
html, you have to use gquery or specific GWT DOM
$("tbody > tr", mygrid).eq(0).after("<tr><td></td></tr>");
$("tbody > tr", mygrid).eq(0).children("td").eq(0).attr("rowspan", "2");

Be aware that changing the html code of a Grid by hand could cause
other problems like certain methods would return incorrect values
(like grid.getRowCount())

Each row in a CellTable or DataGrid represents an object. If you create a cell with rowspan=2, it would break all the logic. At this point you will have to build your own custom table from scratch, including your own DataProvider, SelectionModel, SortHandler, etc.

Why do you need it? I am trying to imagine a use case, but it's a very rare design approach - for a reason.
