Writeback table - form view - "smart" text area

Hi,

I am using the writeback table, form view. I am using "text area" and have put the maximum amount of lines to 10 in my area. The reason for this is that sometimes I will have 10 rows here and need that room to show all of it. It would be great to have the text area be "smart" and only show all 10 rows if there is data taking up the space. If it is white space, condense it. Thanks! Melissa
