Odd separator detection when importing data from attachment

[Ge94]

Hi, thank you for this resource! It's quite useful and intuitive for most things. I really appreciated the examples in your wiki.

I would like to report an odd case. I wrote an attachment in the following format:

TaxID  Color
1117    #999933
1118    #999933
...

The separator is a simple \t. I wanted to pass the attachment through the "parse node states" module, but no data were originally detected even by specifying \t as a separator (regardless of the regex box being ticked or not). After visualising the attachment in the spreadsheet editor, I discovered that the detected regex was [\t ]+ (edit to add: I just noticed an extra white space after the tab in the spreadsheet editor). I am not sure whether this is a standard behaviour, I am working on a Linux distro. Could you please double check this?

As a side recommendation, when studying the different examples I noticed that slightly different things are shown in different wikis. For example, when investigating the "parse node states" function here and here I learnt different things and in particular, I read about the spreadsheet trick when I had already spent quite a while thinking about my issue. Could I suggest taking a look at sections that are kind of repeated throughout the wiki, and provide the same info everywhere?

Thank you again for this cool visualisation tool.
