For hide-block-if I saw the note "This approach works only if there is a single tag inside your named range. If there are multiple tags, the templating engine will switch to logic with hiding content of a single cell".
I need to hide the named range "hideSwapBlock" which has a nested range and table that I use for looping. It currently looks like the following.
I ended up using rule-based conditional formatting in Excel (white text, white background, etc.) to at least "hide" the table when I want to suppress it. Not great, but good enough for now.
I'm not sure where we can make feature requests, but what would be awesome would be a tag like {{value}:hide-range-if(true)} that we could place inside a range that would hide the entire range, even if it had multiple tags in the range.
