Here I tried in Nebula Table with Buttons.Its loading initial page fine.But After clicking some other page it will not override the Button.

package check;

import java.util.ArrayList;
import java.util.List;

import org.eclipse.jface.viewers.ArrayContentProvider;
import org.eclipse.jface.viewers.ColumnLabelProvider;
import org.eclipse.jface.viewers.LabelProvider;
import org.eclipse.jface.viewers.TableViewer;

import org.eclipse.jface.viewers.ViewerCell;
import org.eclipse.nebula.widgets.pagination.collections.PageResultLoaderList;
import org.eclipse.nebula.widgets.pagination.table.PageableTable;
import org.eclipse.nebula.widgets.pagination.table.SortTableColumnSelectionListener;
import org.eclipse.swt.SWT;

import org.eclipse.swt.widgets.Shell;
import org.eclipse.swt.widgets.Table;
import org.eclipse.swt.widgets.TableColumn;
import org.eclipse.swt.widgets.TableItem;


public class ModelSortPageableTableAndTotalChangedExample {

	private static final String[] TOTAL_ITEMS = new String[] { "5", "200",
			"1000", "2012" };
	private static  TableEditor editor;
	public static void main(String[] args) {

		Display display = new Display();
		Shell shell = new Shell(display);
		GridLayout layout = new GridLayout(2, false);
		shell.setLayout(layout);

		Label totalLabel = new Label(shell, SWT.NONE);
		totalLabel.setText("Total:");
		final Combo combo = new Combo(shell, SWT.READ_ONLY);
		combo.setItems(TOTAL_ITEMS);
		combo.select(3);
		int pageSize = 10;
		final PageableTable pageableTable = new PageableTable(shell,
				SWT.BORDER, SWT.BORDER | SWT.MULTI | SWT.H_SCROLL
						| SWT.V_SCROLL, pageSize);
		GridData gridData = new GridData(GridData.FILL_BOTH);
		gridData.horizontalSpan = 2;
		pageableTable.setLayoutData(gridData);

		// 2) Initialize the table viewer  SWT Table
		TableViewer viewer = pageableTable.getViewer();
		viewer.setContentProvider(ArrayContentProvider.getInstance());
		viewer.setLabelProvider(new LabelProvider());

		Table table = viewer.getTable();
		table.setHeaderVisible(true);
		table.setLinesVisible(true);

		// 3) Create Table columns with sort of paginated list.
		createColumns(viewer);

		// 4) Set the page loader used to load a page (sublist of String)
		// according the page index selected, the page size etc.
		List<Person> items = createList(combo);
		final PageResultLoaderList<Person> pageLoader = new PageResultLoaderList<Person>(
				items);
		pageableTable.setPageLoader(pageLoader);
		
		// 5) Set current page to 0 to refresh the table
		pageableTable.setCurrentPage(0);

		combo.addSelectionListener(new SelectionAdapter() {
			@Override
			public void widgetSelected(SelectionEvent e) {
				List<Person> items = createList(combo);
				pageLoader.setItems(items);
				pageableTable.refreshPage(true);
			}
		});

		shell.setSize(400, 250);
		shell.open();
		while (!shell.isDisposed()) {
			if (!display.readAndDispatch())
				display.sleep();
		}
		display.dispose();
	}

	private static void createColumns(final TableViewer viewer) {
		
		// First column is for the first name
		TableViewerColumn col = createTableViewerColumn(viewer, "Name", 150);
		col.setLabelProvider(new ColumnLabelProvider() {
			
			
			@Override
			public String getText(Object element) {
				Person p = (Person) element;
				
				return p.getFirstName();
			}
			@Override
			public void update(ViewerCell cell) {
				Person obj = (Person)cell.getItem().getData();
				
				  TableItem item = (TableItem) cell.getItem();
				 
				 
				
				  Button button=new Button(viewer.getTable(),SWT.NONE);
				button.setText(obj.getFirstName());
				 editor = new TableEditor(item.getParent());
				editor.grabHorizontal  = true;
				editor.grabVertical = true;
				
				editor.setEditor(button , item, cell.getColumnIndex());
				
				editor.layout();
				
			}
			
		
			 
		});
		col.getColumn().addSelectionListener(
				new SortTableColumnSelectionListener("name"));

		
	}

	private static List<Person> createList(Combo combo) {
		int total = Integer.valueOf(TOTAL_ITEMS[combo.getSelectionIndex()]);
		List<Person> names = new ArrayList<Person>();
		for (int i = 1; i < total; i++) {
			names.add(new Person("Name " + i, i < 100 ? "Adress "
					+ Math.random() : null));
		}
		return names;
	}

	private static TableViewerColumn createTableViewerColumn(
			TableViewer viewer, String title, int bound) {
		final TableViewerColumn viewerColumn = new TableViewerColumn(viewer,
				SWT.NONE);
		final TableColumn column = viewerColumn.getColumn();
		column.setText(title);
		column.setWidth(bound);
		column.setResizable(true);
		column.setMoveable(true);
		return viewerColumn;
	}

}

And the Person Class,

package check;

public class Person {
	private final String firstName;
	private final String lastName;
	public Person(String firstName, String lastName) {
		this.firstName = firstName;
		this.lastName = lastName;
	}
	public String getLastName() {
		return lastName;
	}
	public String getFirstName() {
		return firstName;
	}
}
