This feature is a 'magic' button that modifies column width and row height based on contents, to optimize your PowerPoint table size. The feature autofits to create the smallest height table possible (given your table's content).
PPT Productivity PowerPoint add-in's Autofit columns feature retains the width of your table but adjusts each column within that overall width based on each column's contents. Use this feature once you have finished entering data into your table.
Note - the autofit column feature was updated in May 2022 to make the feature faster and to prevent longer words breaking within a column.
If you have applied the Autofit feature and your table is still slightly too long, try adjusting the cell margins.
All PPT Productivity features can be used via the Customizable Shortcut Keys for PowerPoint feature. You can update the shortcut keys to any preferred available combination, but we have created the PPT Productivity shortcut key for autofit optimizing column width
and row height based on content: Ctrl+Alt+Shift+U
