Question

How to implement a table cell in Grails that will have a button and pressing it will change data in a cell of the same row? Lets say table has only id, assignment, accepted (yes, no) fields. The value of accepted is by default no and when you click on Accept button it changes to yes.

Should I use Grails UI Data Table or jQuery Grid?

You can use a submitToRemote button and update the current table row using the update tag. E.g: in your index.gsp:

<table>
<g:each in="${yourDataList}" var="data">
<tr id="dataRow${data.id}">
    <g:render template="tableRow" />
</tr>
</g:each>
</table>

Where your _tableRow.gsp template is something like:

<td>${data.id}</td>
<td>${data.booleanValue}</td>
<td><g:submitToRemote action="updateAction" id="${data.id}" update="dataRow${data.id}" /></td>

Note the attribute value of update is the same as of the <tr> from index.gsp.
Your controller has an action updateAction:

def updateAction = {
    Data data = Data.get(params.id)

    // your business logic
    data.booleanValue = false;

    data.save(flush: true);

    render(template: "tableRow", model: [data: data]);
}

There are obviously other possibilities, but this might be an option for you.
