wpDataTables earns its reputation with non-WordPress data sources: it imports from CSV, Excel, JSON, MySQL queries, and Google Sheets, then wraps the result in a DataTables.js-style frontend with sorting, filtering, and chart integration. That is the right pick when the canonical data lives somewhere outside WordPress and gets refreshed on a schedule. SleekView attacks a different shape of the problem: the data is already in WordPress as CPTs with ACF or Meta Box fields, and the team wants a clean view over it without an import or a SQL query in the middle.

SleekView reads posts and their associated fields directly. There is no "create a wpDataTable, point it at a CSV, refresh weekly" loop — when an editor updates a CPT, ACF, or Meta Box value, the SleekView reflects it on the next pageload. Filters, search, and sort are configured per field on the view itself, not per table inside a DataTables wrapper. View types extend beyond tables to kanban boards (group by status, drag between columns) and feedback boards (cards with upvotes), which wpDataTables does not ship.

wpDataTables wins clearly when the data source is genuinely external: a third-party SQL database, a CSV that updates from a vendor, an Excel report from finance. It also wins on charting — its Highcharts and Google Charts integrations are deeper than SleekView's. SleekView wins when WordPress is the source of truth and the project wants a focused data-view plugin that respects that.

Tables look interchangeable until you look at the data behind them. wpDataTables is built around the assumption that the canonical data lives outside WordPress — in a CSV, an Excel file, a SQL database, a Google Sheet — and that the WordPress page exists to render and (sometimes) chart that imported source. Every part of its workflow optimises for that shape: import once, refresh on a schedule, configure per-table, render through DataTables.js.

The friction shows up when the data already lives as posts with ACF or Meta Box fields. Importing CPT data into a wpDataTable feels like exporting the database to import it back, and keeping the imported table in sync with the live posts adds an extra job no one wanted. SleekView assumes the inverse: the data is already a CPT with structured fields, and the view is just a way of looking at it.

That changes the configuration model — filters bind to fields rather than table columns, view types extend beyond tables to kanban and feedback boards, edits write back to the post directly, and charts are not the headline feature. Both plugins are right for their shape; the choice is a question of where the data actually lives.
