Improve Create/Edit Row (cell/textarea height calculation)

[contreras-jorgev]

On an edit row, we currently show two cells, with 3 line-height each.

Possibilities:

1. Find a way to compute the height, given the text - (may be by measuring the string of the text, we can come up formula to add more lines when there is more text).
2. We may start with cell 1 - 3 lines height, cell 2 - 6 lines height.
3. Allow resizing the textarea (devices with mouse)

Think of more options.

Change title color of first cell. Change the background color of the second cell. Add 'placeholder' hint - like "Enter row content here"
