Support anonymous Table columns without header text

[kravemir]

It would be useful to provide support for anonymous columns, or column renaming with support to define empty name. Maybe Table.Columns.CustomName.

Use case: order notification with following fields:

• description (name of item, plus details, variant,.. ),
• anonymous price per unit of measurement (e.g. 14€ / pc, 19€ / liter, 5€ / kg,...),
• anonymous amount (e.g. 2 pcs, 4 liters, 32 kg,...),
• price contains price per unit * amount).

I don't really want to display names for price per unit and amount columns. These headers prolong the width of these columns, as header is wider than content. And, it's the meaning of the column pretty much obvious from the content of fields..
