Usability at "database command" (Create table) [DONE]

Hi.

I often have to change the data type for my tables as the default does not meet the requirements. Therefore it is necessary to click on the pencil and change the data type. For each field in the table.
It would be more comfortable to skip to the next column with a shortcut or arrows like shown or even have a table with all fields, types an lengths, so that one could change them directly without these steps. Absolutely perfect would be the possibility to upload the table definition via excel (name, type, length,…).
