I want to add a couple of words on that subject.

As you can see from the Share architecture:

The presentation is actually put together with two different kinds of JavaScript frameworks, Yahoo UI library (YUI) and the new one called Aikau ...

You can use capabilities of the YAHOO! YUI library (in my humble experience this is an excellent library!)

Note on the container with the 'bd' identifier, you can often find it in WebScripts. This is how YUI works in Alfresco. Here will be created your table and other stuff...

<html>

<head>
    <title>Adding and deleting rows dynamically</title>
    <link rel="stylesheet" type="text/css" href="http://yui.yahooapis.com/2.8.0r4/build/datatable/assets/skins/sam/datatable.css">

                    oColumn = this.getColumn(target);

                switch (oColumn.key) {
                    case 'delete':
                        this.deleteRow(oRecord);

</html>

One of many examples from Share is the workflow history. As you can see, there is a container with an identifier ${el}-workflowHistory-form-section:

...
<div id="${el}-workflowHistory-form-section" class="workflow-history">
    <h3>${msg("header.history")}</h3>
    <div class="form-element-background-color"></div>
</div>
...

This container is then used to build the widget.

...
var historyContainerEl = Dom.get(this.id + "-workflowHistory-form-section"),
    historyTasksEl = Selector.query("div", historyContainerEl, true);

var historyColumnDefinitions =
[
    { key: "name", label: this.msg("column.type"), formatter: this.bind(this.renderCellType) },
    { key: "owner", label: this.msg("column.completedBy"), formatter: this.bind(this.renderCellCompletedBy) },
    { key: "id", label: this.msg("column.dateCompleted"), formatter: this.bind(this.renderCellDateCompleted) },
    { key: "state", label: this.msg("column.outcome"), formatter: this.bind(this.renderCellOutcome) },
    { key: "properties", label: this.msg("column.comment"), formatter: this.bind(this.renderCellComment) }
];

var workflowHistoryDS = new YAHOO.util.DataSource(this.historyTasks,
{
    responseType: YAHOO.util.DataSource.TYPE_JSARRAY
});

this.widgets.historyTasksDataTable = new YAHOO.widget.DataTable(historyTasksEl, historyColumnDefinitions, workflowHistoryDS,
{
    MSG_EMPTY: this.msg("label.noTasks")
});
...

By using YUI you get all of the features of the DataTable widget, such as sorting, pagination, column reordering, resizing, inline editing, and more... In addition, your code becomes much cleaner due to the html reduction.

To understand how does YUI works, I can recommend you an excellent book by Daniel Barreiro and Dan Wellman - "YUI 2. 8 Learning the Library: Develop Your Next-Generation Web Applications with the YUI Javascript Development Library"

In Start workflow form

In Edit task page

I hope you will get some idea from this control.

On Share configration,

        <field id="myco:userDetails" set="userDetails" label="User Details" >

</script>

If you want this control as, read-only then,add read-only="true" in the share configuration.

<field id="myco:userDetails" set="userDetails" read-only="true" label="User Details" >
            <control template="/org/alfresco/components/form/controls/workflow/userdetails.ftl" />
       </field>

Please note: As of now, this is not production ready and we're also in developement mode. We want to improve this control, please share your idea / comments/ feedback.
