Change Wishlist table-settings

Hi,

my wishlist looks like so:

Product name | Product price |

Product X | 12.99€ | Added on september…

Now my question:

1. Productname is perfect
2. Product price (Headername is perfect)
3. How I can move the price to the Center? Well or to move the Product Price Header a little bit to the right.
4. How I can add a Header for: added on September, For Example: Date or added Date

Thanks in advanced
