Title: Javascript features not working on one table Last modified: February 23, 2022 --- # Javascript features not working on one table * Resolved [philipt18](https://wordpress.org/support/users/philipt18/) * (@philipt18) * [4 years, 3 months ago](https://wordpress.org/support/topic/javascript-features-not-working-on-one-table/) * I have several tables on my site that all work fine, but a new table I’m trying to add isn’t working. None of the JS features like pagination, search, sorting, etc. are present. Is it possible those features don’t work in Preview? I am hesitant to publish it until I can get it working properly. Other than viewing it in a Preview, I’m not sure what is different between this table and others on the site that work. Thanks.

This would also result in the JS features not working, as the external JS library that TablePress uses does not support that. * Regards, Tobias * Thread Starter [philipt18](https://wordpress.org/support/users/philipt18/) * (@philipt18) * [4 years, 3 months ago](https://wordpress.org/support/topic/javascript-features-not-working-on-one-table/#post-15399947) * Hmmm. I published the post and it’s still missing the Javascript features. There are no colspan or rowspan keywords. I now see you said it should show up in the page preview, but it did not.

The problem is in line 7 of the table (הרב שמואל אליהו). There, the link HTML code is missing the text and the closing `` tag. This breaks the table DOM structure so that the JS features can’t work. There are few more similar errors, see [https://validator.w3.org/nu/?doc=https%3A%2F%2Fbloodandfrogs.com%2F2022%2F02%2Fan-ultra-orthdox-view-of-jewish-names.html](https://validator.w3.org/nu/?doc=https%3A%2F%2Fbloodandfrogs.com%2F2022%2F02%2Fan-ultra-orthdox-view-of-jewish-names.html) For example, there’s a case where the `"` after the URL is missing, or where the `=` between the `href` and the `"https:...` is missing. * brain8torm: If your table also does not use the `#colspan#` or `#rowspan#` keywords, there’s also some invalid HTML code like in the case above. I would also recommend to check the page HTML with the W3 Validator at [https://validator.w3.org/](https://validator.w3.org/). * Regards, Tobias * [brain8torm](https://wordpress.org/support/users/brain8torm/) * (@brain8torm) * [4 years, 3 months ago](https://wordpress.org/support/topic/javascript-features-not-working-on-one-table/#post-15401640) * Plugin tested on empty website with theme Twenty Twenty-One with simple table without #colspan# or #rowspan# * Plugin Author [Tobias Bäthge](https://wordpress.org/support/users/tobiasbg/) * (@tobiasbg) * [4 years, 3 months ago](https://wordpress.org/support/topic/javascript-features-not-working-on-one-table/#post-15401662) * Hi, * Can you please post a link to the page with the table where this problem happens, so that I can take a direct look (or provide the table as an exported CSV file)? Thanks! The error message indicates that some cells are missing, which is the used language for “invalid HTML code” in one of the cells (because this spills into adjacent cells and thus breaks the table HTML code). * Regards, Tobias * [brain8torm](https://wordpress.org/support/users/brain8torm/) * (@brain8torm) * [4 years, 3 months ago](https://wordpress.org/support/topic/javascript-features-not-working-on-one-table/#post-15401769) * sorry. it’s working. colspan found. Then colspan can only be used without activating Datatables. How then to use colspan to create table partitions? * Plugin Author [Tobias Bäthge](https://wordpress.org/support/users/tobiasbg/) * (@tobiasbg) * [4 years, 3 months ago](https://wordpress.org/support/topic/javascript-features-not-working-on-one-table/#post-15401773) * Hi, * Indeed, `#colspan#` and `#rowspan#` can only be used when the “Use DataTables” checkbox is turned off. This is a limitation of the external DataTables JavaScript library that TablePress uses. Unfortunately, I’m not aware of a way to use the JS features in a table that has combined/merged cells.
