I'm using version 4.9.5. I have two issues : 

1) I'm using wpdatatables to query and edit tables in MYSQL. Since MYSQL only accepts dates in the YYYY-MM-DD format, I find it puzzling why this format is not in the drop-down of date display choices for wpdatatables. The result is that when filtering the data, the correct rows only appear when entered in the YYYY-MM-DD format, despite being displayed in one of the other formats offered by wpdatatables.

2) For many simple queries (select * from table) Excel-like tables often show no data while the standard view works fine. When the Excel-like tables do show data, it does not fit on a single page, unlike the standard view. Setting scrollable both on or off doesn't help. I can squish the column contents by selecting off on scrollbar and on for limit table width, but then the columns are too narrow to see the entries. The Excel-like tables overflow out of the page frame in both the vertical and horizontal directions.

I just downloaded the new version (2.2?) and the circular arrows are gone. The formatting issues and blank table problem are still there for the Excel view. I can get rid of the blank table problem by limiting the size of my search to a few rows, but I don't want to do that. It would be tough to set up a test environment. I could do it if it's really needed.

Also, still don't see a YYYY-MM-dd date format, which is the native format used by MySQL.

Thanks, I see that "pagination" and "scrollable table" are "not yet supported." But I don't see why they are not supported yet. How useful is a giant excel table w/o pagination or being scrollable?  I just downloaded today's update. Still no support for the MYSQL standard YYYY-MM-DD format and the problem of displaying no data for a large table in the Excel view is still there, which I guess is the not supported for "server-side processing/very large tables". One of my tables which doesn't show up in the Excel view is only 6000 rows, which I would not classify as "very large."
