Answer 1

The outcome of your html should look something like this
<input type="text" name="Code" value=""/>
...
<table>
<thead>
<tr>
<th>#</th>
<th>Name</th>
</tr>
</thead>
<tbody>
<tr>
<td>1</td>
<td><input type="hidden" name="InvoiceItems[0].Name" value="InvoiceItem1"/></td>
</tr>
<tr>
<td>2</td>
<td><input type="hidden" name="InvoiceItems[1].Name" value="InvoiceItem2"/></td>
</tr>
<tr>
<td>3</td>
<td><input type="hidden" name="InvoiceItems[2].Name" value="InvoiceItem3"/></td>
</tr>
</tbody>
</table>
<button type="submit">Submit</button>
</form>
This way you can use plain form submission or ajax
// assuming you have only one form. otherwise use more specific selector
var $form = $("form");
var data = $form.serializeArray();
var url = $form.attr("href") || document.URL;
$.post(url, data, yourCallbackFunction);
The rest is done by ModelBinder. The key part is to maintain InvoiceItems indexes. They must start from 0 and be sequential. i.e. 0,1,2,3 etc.. If you skip some index, modelbinder will end binding your list where indexes are broken.

lists can be represented by quasi-2-dimensional-arrays:
$arr =
array(
array(
{
"key":"value",
"key2":"value2"
},
{
"key":"value",
"key2":"value2"
}
),
array(
{
"key":"value",
"key2":"value2"
},
{
"key":"value",
"key2":"value2"
}
)
);
(json_encode)
can be read e.g. with $val = $arr["0"]["0"]["key2"];
this is just an example > use and combine Array-, Object- and Json-Syntax to get your list match your needs. working with json is very handy and features very "sourced" and object-oriented coding and easy data handling.
ps: to me your question seems rather unclear, dont know what you are exactly aiming at...
