I want to use the MB Custom Table to allow my client an easy way to edit custom post types.
But I don't understand how to prepare the table.
I followed this page: https://docs.metabox.io/extensions/mb-custom-table/ , but I find it difficult to understand exactly what to do, or where I should place that code you provide.
I hope you can help me here, so I won't need to spend more money on tools like Admin Columns Pro etc'.
No, maybe I think of the "MB Custom Table" in a wrong way.
What I want is to allow my client to edit the posts while they are in the wp admin section, and looking at the admin post list.
Something like the plugin "wp admin columns" does.
So instead of entering into each post to make changes, they could do that in a table view on the admin side.
That way they can make quick changes to field I define, but in "excel" view...
I think you misunderstand the purpose of the MB Custom Table extension. It doesn't provide an Excel-like UI for users to enter the data (for that purpose, an extension with name "Data Table" might be a better idea). Instead, it save custom fields into a custom table in the database. So, in this situation, table means database table. The whole idea of the extension is changing how we save data: from post meta to custom table. That's it.
As far as I know, there's no solution for this problem yet. Why don't you let your client edit the data in a real Excel/CSV file and use a CSV import plugin. There are many of them available for free on .org.
