SilverStripe Template - how to access keyless values - silverstripe

Question

How can I show a 2 dimensional array as html table per SS template? Since there are just values and no keys for the Child/Row DO I'm struggling to show theme per template. How do I call theme in template or how would you do?
array showItems
0 =
0 = Title
1 = Text
...
1 =
0 = Title
1 = Text
...
...
PHP
public function showItems() {
$result = ArrayList::create();
$table = $this->getItems();
foreach ($table as $row) {
$r = DataObject::create($row);
$result->push($r);
}
return $result;
}
Template:
<% if $showItems %>
<table>
<% loop $showItems %> // loop for rows
<tr>
<% loop $Children %> // loop for cells
<td>$Me</td>
<% end_loop %>
</tr>
<% end_loop %>
</table>
<% end_if %>

Use ArrayData for each row, but as you know what each column is standing for I'd add keys to it, e.g. using array_combine()
Untested:
public function showItems() {
$result = ArrayList::create();
$table = $this->getItems();
$keys = array('ID', 'Foo', 'Bar');
foreach ($table as $row) {
$r = ArrayData::create(array_combine($keys, $row));
$result->push($r);
}
return $result;
}
Another possibility:
public function showItems() {
$result = ArrayList::create();
$table = $this->getItems();
foreach ($table as $row) {
$r = ArrayList::create($row)); //you can oop over an ArrayList
$result->push($r);
}
return $result;
}
In your template you might do:
<% if $showItems %>
<table>
<% loop $showItems %> // loop for rows
<tr>
<td>$ID - $Foo</td>
<td>$Bar</td>
</tr>
<% end_loop %>
</table>
<% end_if %>
Another possibility:
public function showItems() {
$result = ArrayList::create();
$table = $this->getItems();
foreach ($table as $row) {
$r = ArrayData::create(array('Row' => ArrayList::create($row)))); //you can oop over an ArrayList
$result->push($r);
}
return $result;
}
<% if $showItems %>
<table>
<% loop $showItems %> // loop for rows
<tr>
<% loop $Row %>
<td>$Me</td> //dunno if that really works...
<% end_loop %>
</tr>
<% end_loop %>
</table>
<% end_if %>
