Hi @Jopoleon, I will look into this as soon as possible, later today.

@Jopoleon, I just did a push to fix the error, please download again the library and close this issue if the problem is resolved. kingtable.js here in GitHub. I am publishing the library in these days and still fixing some things.

Hello, Roberto. I tried to fix it too today, and I found out, that error happens in line 66 in kingtable.js file. This line is some weird regex if condition. I just commented it with // and everything worked just fine . Thanks for answer. пятница, 05 мая 2017г., 23:28 +03:00 от Roberto Prevato notifications@github.com :

Great! :) that regular expression is used to highlight matches from text search. Code is weird because I need to escape HTML fragments, around portions of HTML that allow to obtain the highlighting.

For example:

// looking for "smo",

// string "Smokowski" is converted to:
<span class="kt-search-highlight">Smo</span>kowski

Please update the library anyway, since I corrected also other things related to the same issue.

Closing, as the problem was resolved. Null values were causing problems in automatic sorting of strings that can be sorted by their numeric part (for example "100%", "50.20 EUR", etc.).
