Feature request - Column name attribute as expression

[ena1106]

If you define columns in HTML as in the "Expressive Columns" live demo, the name attribute is always treated as a string even if it's an angular expression. <column name="Gender" flex-grow="1"> {{monkey}} {{$cell}} </column>

It would be useful to let it be an expression too, mostly for translation purpose. For example using angular-translate you could write: <column name="{{'users.gender'|tranlsate}}" flex-grow="1"> {{monkey}} {{$cell}} </column>

Thank you for the great work.
