can NOT automatically post, you need export results from response table to a pdf/xls/csv file and manully post to you web page.
Actually you can publish the responses and embed it in your website.
Open you form
Click on the Share button in the bottom left corner
Click on Publish Responses
Click on the Publish button in the dialog
You will see a "Published" icon on the bottom bar
Hover it to expend it (if it is not already expended)
Click on "Copy embed code"
You can then use this embed code in your website. As responses are coming it the table will reflect the lastest data.
You can also just have a link to the published data (use "Copy link" instead) if you don't want to embed the data in your website.
Hope this helps
