I'm transitioning some tables from Swing to FX.
I am trying to create a custom horizontal oriented TableView kind of like what is asked about here.
I utilized this method to wrap and display my column of data. I did a bind between two table scrollbars to get a "row header". Here is what the entire thing looks like:
Then I checked how well TableView handled loading a large amount of data. I created a basic multiplication table with 10 columns and 100,000 rows. After the initial load-in, the table was incredibly responsive and the vertical scrollbar movement and had no issue.
My issue came when I add more columns. I believe because of the way that TableView expects data to be in rows instead of columns that when I add 10,000 columns and 50 rows the entire TableView component was unresponsive. It also took significantly longer to load-in than the 10 columns, 100k rows.
At ~4k columns and 50 rows, the table responded well to the horizontal scroll, but the vertical was very slow to respond, which is why (apart from the inherent structure) I was lead to believe TableView prefers row data to column.
Is there a way around the unresponsiveness that preferably:
- Keeps the columns as the dataset
- Doesn't involve going back to
JTables - Avoids pagination
I found this post, but it did not seem helpful and the OP went back to JTables in the end. On the other hand, this was 4 years ago and a slightly different case.
Please note I am new to posting so let me know if more info is needed.
