Manipulate column render cell

You can set a callback to manipulate the render of a cell.
If the callback returns nothing, the cell will be empty.

<?php
...

$grid->setSource($source);

$grid->getColumn('my_column_id')->manipulateRenderCell($callback);
...

$grid->getColumn('my_column_id')->manipulateRenderCell(
    function($value, $row, $router) {
        return $router->generate('_my_route', array('param' => $row->getField('column4')));

<?php

$grid->setSource($source);

// Add a column with a rendering callback
$MyColumn = new TextColumn(array('id' => 'Another Column'));

$MyColumn->manipulateRenderCell(function($value, $row, $router) {
    return $router->generate('_my_route', array('param' => $row->getField('column4')));}
);

$grid->addColumn($MyColumn);
