Our production application usually loads 200 rows and lets the user load as many more rows as they see fit. It also provides a "fit all columns" function which will fit all columns of the table. Users are fine with a few seconds of blockage if they have loaded thousands of rows. But if the "fit all columns" function will no longer work, they will report a bug which I will not be able to fix, if JavaFX suddenly refuses to iterate over all the rows as it does now. So maybe we should: * Provide an API that let's the client specify how many rows should be taken into account * Make resizeColumnToFitContent available for clients > > At the same time the user might simply double click on the header again (or > better, just resize the offending column like they used to do since time > immemorial) once a wide cell comes into view. > > Basically, I don't think the new API is required in this particular case; I > think it's a bug and it should either size the visible rows or (visible + > some margin).

And it is a totally separate issue. ------------- PR Comment: https://git.openjdk.org/jfx/pull/1358#issuecomment-1928861769
