Render table/custom ui from comma separated string

I’m trying to show the ranking of my son’s hockey team on HA. I wrote a little script that grabs the scores from a webpage. This results in a file called “standen.txt”
This file contains one string (which I can make different if that would make things easier):

1;Warande JB2;1;1;0;0;11;1;0;2;Pelikaan JB1;1;0;1;0;2;2;0;3;Push JB2;1;0;1;0;2;2;0;4;Drunen JB1;0;0;0;0;0;0;0;5;Prinsenbeek JB1;0;0;0;0;0;0;0;6;HSD JB1;1;0;0;1;1;11;0

As you can see, the ranking is inside that string.

I have a cron job that updates this file every x hours and I have a platform-sensor that reads this file:

- platform: command_line
command: "cat  /tmp/standen.txt"
name: File value

So I would like to show the rankings as a table inside HA, and not as an iFrame.

I think I will need a custom-ui for this, but I really don’t know where to start.
It would be nice to show all the columns, but just the first three values would be nice in a Table-form

Any ideas?
