First of all a big thanks to Adrian, making this possible! 
This is a part of the advanced flow, for 10 tables, of which 5 headers that change uppon a situation.
I implemented an image (png transparant image of 100x100 pixels) that I have loaded with the Homey Gallery App to the Homey Pro.
In developer tools you can overview all your images, and find the correct reference link to use in your HTML code for reference. I have put the image in a table as it is easier to correctly align an place it where you want to.
The table is created with the simple HTML table code.
< table > to start a table
< tr > to start a row
< td > for data (or you can use < th > for a header.
And then to close
< /td > < /tr > and < /table >
Further I used spaces to create empty columns for better layout.
You can do so by adding " & emsp ;" for a bigger space, of " & ensp ; " for a smaller space.
Also you can use < big > for a larger font size and < b > < i > < u > for other layout options (just google HTML and you can find a lot 
)
Finally you can include value’s from your homey or logic variables by using the normal input label in your flow creator.
Then you end up with something like this above.
I now have a time based update every 5 minutes, but I am struggling to update the actual dashboard. I have read in the above comments that I am not the only one. So somehow it will only update the data when refreshing the complete dashboard, and then trigger a manual update on the flow cards. Would be great if it could be solved to update in the background as well.
