table without table headers

is it possible to create a table without headers.
Also it should be possible to perform sorting and filtering on that.

Yes:

table.setColumnHeaderMode(Table.COLUMN_HEADER_MODE_HIDDEN);

You sort and filter by calling the appropriate methods, e.g sort via
setSortContainerPropertyId()
and filter by filtering the Container (talbe.getContainerDataSource() and assuming it’s Filterable)

See

for more info.
