@palisetty if you are able to see visualization then you can check just below the search bar that you are under the Visualization tab. All you need to do is that click on the Statistics tab and the Tabular results will show up.
For example if you have searched Splunk's _internal index, you can select a field like sourcetype and then choose Report > Top values by Time. If you have any visualization selected last, it would show the Visualization tab with that viz. selected. Here, you can see Statistics tab and click on the same to get the tabular output.
