You could use css and give each column a id or class, here is a rough example
<style>
#column0 {
text-align:left;
}
#column1 {
text-align:center;
}
#column2 {
text-align:right;
}
</style>
<table id="table" border="1">
<tr>
<th colspan="3" >{{msg.title}}</th>
<tr>
<th>Omschrijving</th>
<th>Prijs</th>
<th>Eenheid</th>
</tr>
<tbody>
<tr ng-repeat="row in msg.payload">
<td ng-repeat="item in row" id="column{{$index}}">{{item}} </td>
</tr>
</tbody>
</table>
