Currently i am working on task which requires me to update TableViewer data on top of existing one.

I have a view which extends ViewPart and which displays data in TableViewer.

While loading view i am setting TableViewer data
ex:
viewer.setContentProvider(ArrayContentProvider.getInstance());
viewer.setInput(new String[] { "One", "Two", "Three" });

now i need to update TableViewer without loosing existing data.

i am doing this but i don't see TableViewer is getting updated

Display.getDefault().asyncExec(() -> {
viewer.setContentProvider(ArrayContentProvider.getInstance());
viewer.add(new String[] { "Four", "Five"});

viewer.getControl().setRedraw(true);
viewer.refresh();
});

Any idea why ViewPart tableviewer is not updated new data?

Thanks
Nagaraj
