Wanted a round shaped image in table visual

Hi Anonymous 

After testing, you cannot change the shape of the image in table visual, but you can use the custom visual: html content , it can use html to custom the image.

you can refer to the following link.

Use HTML to make Power BI images/icons more interesting (vahiddm.com)

and you can create a measure, then put the measure into the 'html content' visual, you can refer to the following code.

Black and white = 
Var _Image1 = "https://powerapps.microsoft.com/images/application-logos/svg/powerbi.svg"
Return
"<style>
img {
  transition: filter .5s ease-in-out;
  filter: grayscale(0%); 
  border-radius: 50%;
}
img:hover {
  filter: grayscale(100%);

  blur(5px);
}
</style>
<img src='" & _Image1 & "' >"

Output

Best Regards!

Hi Anonymous v-xinruzhu-msft, thank you for providing the solution. However, I'm uncertain if it will meet my needs. Specifically, I require a round-shaped image within a column of a table visual, aligned with another column, and it should respond correctly to any applied filters. Since this solution seems to be implemented in a separate custom visual, I'm unsure if it will fully fulfill my requirements.

Currently im doing exactly this with flipdash.io. See blog below about this topic, I hope it helps.
