TextField of editable table larger than column width


if a table is set to editable, the TextFields for editing single cells seem always to have the same size, even if the column width is smaller than the TextField:

You can see this in the Vaadin Sampler:

Just change the table to editable in the settings, and in the “Code”-column all TextFields are cut off due to the column width.

Is it not possible to automatically adjust the TextFields to the actual column width?
Is there a ticket for it or a workaround available?
I am using Vaadin 7.7.0.
