llunak: 16384 columns in Collabora Online
Since the Calc core is the same, the underlying functionality works just like in LibreOffice. But the online functionality presented some additional challenges that needed handling, as having more cells in a spreadsheet may mean more data sent over the network, slowing things down. There definitely used to be problems with large spreadsheets, as the tiled rendering used by Online in fact was already limited to 500000 rows compared to 1048576 rows of the desktop version (in fact, git history shows that this started at only 1000 rows initially and then was continually raised over the time as things improved). So together with raising column count to 16384 I have raised this to the normal 1048576 rows as well.
[...]
Now with hopefully all performance problems solved, Collabora Online 22.05 should support these spreadsheet sizes just as fine as the desktop version.

Tomaz's dev blog: Chart Data Tables
Chart data table is a feature of charts, that presents in the chart area a data table with the values that are visualised by the chart. The data table is positioned automatically at the bottom of the chart, and can for certain chart types replace the X-axis labels. Until now this feature has been missing in LibreOffice, but thanks to the funding of NGI, it is now implemented.
