You can manage list table columns with your own custom code, such as described in this article. But it sounds like this admincolumns plugin manages much of this for you. I suspect columns added by custom code from that article and columns added by the plugin can likely cohabitate together, but I cannot be certain.
If you need to modify what the plugin does, I suggest asking for advice through the plugin’s dedicated support channel.
I think the plugin doesnt disturb because I created my self a column by code and then I could use admincolumns just to modify the order of this new column. I think maybe it’s better to use a filter already in use and modify it. I’m thinking to the filter “all the dates”. I dont mind to filter by periods, besides I change the publishing date just to push an apartment /post above or down others, so I could use this selector for a new purpose. Better a new selector or modify what is in use by default?
If you can make the existing filters work for you, then that’s the simplest solution. But if a custom filter would make property administration easier, it might be worth the effort to add one.
FYI you can only filter by valid URL query string parameters, for example: test.sacconicase.com?tipologia=villa
Doesn’t have to be by a column in the table. It is possible to add custom query string variables though. But it still needs to be something that can be made to work with WP_Query and “pre_get_posts”.
