How can I set No as a default value dropdown list within input table?

Hi i have input table, one columnhas dropdown list as yes or no. But when i try to fill it, i see blank option along with yes and no, can it be avoided or can i have No set as default.

Unfortunately, there is no way to set default values in dropdown fields in the Input table. As a workaround, you can use this app to generate a pre-populated form URL: https://prepopulate.jotform.io/ 

Here is a related guide for reference: Prepopulating-Fields-to-Your-JotForm-via-URL-Parameters 

Then you can create a URL that you can share with your users so when they click the prepopulated form URL, the dropdown will be pre-filled with value as No. They can then select the value from the dropdown and change it to Yes as required.
