Kutbuddin,
Take a look in
http://api.simile-widgets.org/exhibit/2.2.0/scripts/ui/widgets/collection-summary-widget.js
Find
Exhibit.CollectionSummaryWidget.prototype._reconstruct
You need to make a copy of that function and include it after you
include exhibit-api.js in order to override the default behavior. Then
remove the check for originalSize > 0. That check causes the summary
widget to be empty when there is no item at all.

This is in
http://api.simile-widgets.org/exhibit/2.2.0/scripts/ui/views/tabular-view.js
Look for
Exhibit.TabularView.prototype._reconstruct
Make a copy of that function. Note the check items.length > 0. The
second comment in that if statement is wrong: it should say "Create
table" rather than "Sort the items". Move the chunks of code that create
the table and create the column headers outside the if statement.
