colSpan not working in the backend view

[patrickklosedev]

I have the following configuration in the file tt_content.php:

According to an example of this extension, this should lead to having the first row span the two columns that follow.
However, this is the result in the backend:

Is this a bug or did I used "colSpan" wrongly?

TYPO3 12?
"Layout-Mode"

but "Language-Comparison-Mode"

this is same as core backend_layout rendering behaviour.

Yes, Typo3 V12.
And even in Layout Mode, it doesn't work.

When I check the source code, the defined colspan is not used.
By changing this value directly in the source code, it works (temporary):

[achimfritz]

this is my source-code (with EXT:container_example, https://github.com/b13/container-example/blob/master/Configuration/TCA/Overrides/tt_content.php#L11)

ah i see ..., you have to write "colspan" instead of "colSpan" in your configuration

[patrickklosedev]

Unfortunately, this doesn't work either...
I already have this tried before.

I will try out your code example and get back to you.

Same issue in v12.

Same problem here with TYPO3 11 and latest EXT:container. PHP 7.4 or 8.2 doesn't matter.

It works in column view, but not in language view.
