Extract / Convert Information From A Listview To A DataTable?

I have a relatively simple Listview that suddenly needs (due to new requirements) to have it's 'layout' extracted to a DataTable so that a common routine can convert it to an Excel spreadsheet for export purposes.

The ItemTemplate is just a series of Table Rows with some text, data-bound labels and textboxes with validators in the cells.

Usually, when trying to pull out a particular value (like what was entered into a text box), I use the ListViewItem's .FindControl method.

For Each objItem As ListViewItem In lvwOptions.Items
Dim objTextHrsLabor As TextBox = CType(objItem.FindControl("txtHrsOptByLabor"), TextBox)
decHours = CDec(objTextHrsLabor.Text)
Next

In this case, however, I'm trying to take all the data displayed - all the 'rows and columns' of the table that was created.

Inside the ForEach / Next loop of ListViewItems, I started a ForEach/Next loop of Controls for each instance's controls but I got some really strange results returned (like controls that had a couple of table cells in them).

I get the sense I'm headed in the wrong direction. All I want is for the nicely-formatted 5-line, 6 column table to be converted to a 5-line, 6-column data table.
