Ng-table: How to show horizontal scroll bar when there are many columns needed to be shown in one table?

Create a container above it.
<div id="container"> <!--your table --> </div>
And using css do:
#container { width:100%; overflow: auto }

@AmitMY will hide the pager

+1，need a container for the table element

you need to surround table with div say
<div id="container"><!--table here--></div>

In css apply following style to container div
#container{white-space:nowrap; overflow: hidden;}

then apply following style to your table
.table{display:block;overflow-x:scroll;}

This will add horizontal scrollbar just below the table and before the pager div.
