Advanced SWT table widgets

Question

There are a couple of "advanced" table/spreadsheet SWT widgets out there (Nattable, Nebula Grid), but none of them support really large datasets. Nattable is the one which comes closest, but it still has limitations in the datatypes it uses causing the number of rows in the table to become far to limited.

I need to be able to represent at least 2^32 rows, preferrably 2^64.

Answer 1

SWT Matrix breaks the capacity bariers allowing any BigInteger amount of rows or columns. It is closed source, but free for private and non-commercial use. Early alpha release though at this point.

Answer 2

What's wrong with SWT.VIRTUAL with a reguar table? You can then use a LazyContentProvider, which gives you a callback for loading what's needed in the view.

Something like this...

TableViewertableViewer = new TableViewer(parent, SWT.VIRTUAL|SWT.BORDER|SWT.V_SCROLL);
// skipping the noise
tableViewer.setItemCount(100000);
tableViewer.setContentProvider(new LazyContentProvider());
tableViewer.setLabelProvider(new TableLabelProvider());
tableViewer.setUseHashlookup(true);
tableViewer.setInput(null);
