I’m trying to create a grid where i want to use rows:(auto,auto,1fr), to determine the height of the top 2 rows.
More specificly i want the left column to determine the height.
In the right column i want an image to cover the entire rowspanned cells, similar to the fit parameter on image..
At the moment you can still see the background of the topright cell, and i want the image to cover the entire cell, so that you no longer see the aqua-blue in the example.
Setting a height on the image of 100% or 1fr, results in the image determining the height of the 2 top rows. I want the left cells to determine the height of the top rows and the right to just adjust to the height of the left cells.
(How) can i do this in typst?
PS. Im looking for a solution in Typst not SVG because i want to use bitmap images. The svg is just an example.
I managed to find a solution by measuring/calculating the height of the left column and then setting the height of the image in the right column explicitly.
The code containing the solution:
#let imagecontents = "<svg class=\"svg-icon\" style=\"width: 1.01171875em; height: 1em;vertical-align: middle;fill: currentColor;overflow: hidden;\" viewBox=\"0 0 1036 1024\" version=\"1.1\" xmlns=\"http://www.w3.org/2000/svg\">
<rect width=\"100%\" height=\"100%\" fill=\"gray\" />

For the moment, this is only present in tablex package (which inspired Typst 0.11’s new table API) through the fit-spans: (y: true) setting. It is, however, generally discouraged to use tablex as most of its features have been ported to built-in tables and grids (but specifically not this feature at the moment), and tablex compiles much slower than those. Still, here’s how it would look like:
