align linkbutton in datagrid

[crosemffet]

after some efforts, and read carefully differents posts, finally found how to add a link button inside a cell in a datagrid.
the problem now is the button doesn't show aligned with the rest of the row (and so looks really bad...)(please see the attached image...)
my code is:
...for the row:
<th data-options="field:'tasks',formatter:formatRowButton">Tasks</th>
... for the creation of the button
onLoadSuccess: function(data){
   //create the grid buttons
   $(this).datagrid('getPanel').find('a.gridButtons').linkbutton();
... and finally
function formatRowButton(val,row){
   return '<a href="#" class="gridButtons" data-options="plain:true">A Link</a>';
}
what's wrong with my code..?
in what place should I put the align instruction (top?.. middle.? bottom..?)
thanks in advance....

Set rows with larger height value.

Code:

	<style type="text/css">
		.datagrid-row{
			height:35px;
		}
	</style>

Or call 'fixRowHeight' method after the linkbutton is created.

Code:

onLoadSuccess: function(data){
   //create the grid buttons
   $(this).datagrid('getPanel').find('a.gridButtons').linkbutton();
   $(this).datagrid('fixRowHeight');
}
