Toggling column visibility removes table header title


Hi,

I am using KTDatatables Metronic v7 and want to toggle column visibility. 


datatable.column(parseInt(val)).visible(false);
where val is the column index.

This works perfectly in terms of removing the column from view and setting the parameter to true again to bring it back. However on bringing it back the table header column title is not restored. I need to execute an extra 

datatable.reload();
to get back my table header for the column I previously removed from view.

How can I remove a column from view and bring it back including the table header?

Hi Tristan,

Sorry for the inconvenience. Please note that we have stopped providing updates for KTDatatables since Metronic v8. For future data table updates, we use the Datatables.net plugin.

In our online demo, showing and hiding a column is working.
https://preview.keenthemes.com/metronic/demo1/crud/ktdatatable/api/methods.html

In file;
\theme\demo1\src\js\pages\features\ktdatatable\api\methods.js

Please try to use datatable.columns instead of datatable.column function.


datatable.columns(parseInt(val)).visible(false);



Thanks

Hi!

I tried to use columns instead of column, but this give error:

TypeError: undefined is not an object (evaluating 'delete options.columns[index].visible')

\theme\demo1\src\js\pages\features\ktdatatable\api\methods.js

and applied it to my code. It works now. Thanks!
