WP Table Manager (by JoomUnited) is a polished spreadsheet-style table editor for WordPress. It ships an Excel-like grid in the admin UI, formula support, cell styling, CSV and Excel import, Google Sheets sync, and a chart module. For teams who want to manage tabular content in a familiar spreadsheet interface inside WordPress, the feature surface is rich and the output is well-designed.

SleekView starts from a different shape of the problem. The rows are not cells in a spreadsheet, they are CPTs. The columns are not cell formulas, they are ACF or Meta Box fields. The source of truth is the post, not a shadow spreadsheet that needs to be kept in sync. Instead of opening a spreadsheet grid, SleekView reads the post type directly and renders a configurable view over the same fields editors already update.

WP Table Manager wins clearly when the work is genuinely spreadsheet-style: cell-by-cell editing, formulas, manual or imported rows, and chart output. SleekView wins when the rows mirror a CPT and the view is supposed to follow the data automatically, especially when filters need to bind to ACF or Meta Box fields or when the team needs kanban or feedback layouts. Many sites end up keeping both for different jobs.

WP Table Manager is built around a familiar metaphor: a spreadsheet grid inside WordPress, with cell editing, formulas, styling, and import flows from Excel, CSV, and Google Sheets. That metaphor is right for sites that genuinely want to manage tabular content the way they would in a spreadsheet, especially when chart output is part of the deliverable. The plugin's depth in that area, formulas, cell styling, sheet syncing, and a chart module, is exactly what those sites need.

The friction shows up the moment the rows mirror a CPT. Maintaining a spreadsheet that mirrors a CPT means keeping two copies of the same data in sync, and every CPT update becomes a re-import job that someone has to remember to run. The view stays table- and chart-shaped even when the requirement has moved on to a kanban or a feedback board.

SleekView starts from the inverse assumption: the data is already a CPT with structured fields, and the view is just a way of looking at it. There is no shadow spreadsheet to keep in sync, because the view reads the post list directly. Filters bind to fields, sort and search live on the view, edits write back to the post, and the same view definition can render as a table, a kanban board, or a feedback board.

The two plugins compose well rather than compete, with most sites that try both keeping WP Table Manager for spreadsheet-style work and reaching for SleekView the moment a CPT is in the picture.
