Adding markdown image in dashtable

Hello,

I would like to create a dashtable with one of the columns haveing a markdown image like it is in the image:

I have tried using the presentation of the column as markdown and type as text but this brings errors when the text is in this format:

<span style="background-color:#5DCBEF"> ⬤ </span>

Does anyone know how else i can put the colored dot inside a dashtable cell?

Hi @tanya

Currently this is not possible, but good news: This will be in the next release of Dash :confetti_ball:

See this pull request for more details and examples.

Hi @tanya

You also can use emojis to do that.

See this example using a box image to simulate a checkbox:

Hi @Eduardo, thanks. I used emojis but i could not customize them to the color i wanted. Do you know if that is possible?

Hey @tanya

I do not know if it is possible. :thinking:
You have different color options but limited:

Another alternative is taking the white circle or the white medium square and combine with background color. :woozy_face:
