    copied!<p>i have a table contains 3 columns, when the user clicks in one of them the table should be sorted, i'm using AsyncDataProvider, the sort for the first column works fine, so i should do the same to the others columns. this is the code : </p> <pre><code>AsyncDataProvider&lt;PermisoUI&gt; providerPerfiles = new AsyncDataProvider&lt;PermisoUI&gt;() { @Override protected void onRangeChanged(HasData&lt;PermisoUI&gt; display) { if(sortedPermiso) { sortedPermiso=false; class TipoCuotasComparator implements Comparator&lt;Object&gt; { public int compare(Object l1, Object l2) { PermisoUI o1 = (PermisoUI) l1; PermisoUI o2 = (PermisoUI) l2; return o2.getId().compareTo(o1.getId()); } } Collections.sort(listPermisos, new TipoCuotasComparator()); }else { sortedPermiso = true; class TipoCuotasComparator implements Comparator&lt;Object&gt; { public int compare(Object l1, Object l2) { PermisoUI o1 = (PermisoUI) l1; PermisoUI o2 = (PermisoUI) l2; return o1.getId().compareTo(o2.getId()); } } Collections.sort(listPermisos, new TipoCuotasComparator()); } int start = display.getVisibleRange().getStart(); int end = start + display.getVisibleRange().getLength(); end = end &gt;= listPermisos.size() ? listPermisos.size() : end; List&lt;PermisoUI&gt; sub = listPermisos.subList(start, end); updateRowData(start, sub); } }; providerPerfiles.addDataDisplay(CellTblPermisos); //Sorting Column AsyncHandler columnSortAplHandler = new AsyncHandler(CellTblPermisos); CellTblPermisos.addColumnSortHandler(columnSortAplHandler); CellTblPermisos.getColumnSortList().push(permisoColumn); providerPerfiles.addDataDisplay(CellTblPermisos); providerPerfiles.updateRowCount(listPermisos.size(), true); PPerfil.clear(); PPerfil.add(CellTblPermisos); </code></pre>

An individual column

Larger individual text columns get their own page to allow for proper reading.
