When I create a table in app designer (evenif inside a layout), there will be a white area under the table if my rows are not enough (see first screenshot).

On the other hand, fairly, more rows will result in a scroll bar.

But I would like to obtain, in case of a few rows, a result like the one in the second screenshot.

Is it possible to achieve this result?

Thank you

it wouldn't work with the "fit" gridlayout, but if it is really important to you, what i have done in the past is to measure the number of pixels associated with each row and multiply that by the number of rows currently in the table, plus 1 pixel for each row plus 2 (for the borders), and the height of the header row if you have one.

you can set the height (Position(2)) of the uitable any time the number of rows of data changes or on resize (I haven't tried with the resize).

How can I know or measure each row height in pixels?

When I did this in the past, I did trial-and-error. The font size you use is a good starting point. Or just screenshot and count pixels.

Look into uigridlayout with the "fit" keyword for row heights

Hi Alex,

a quote from the online guide: For non text-based components, 'fit' height is based on the default size of the component and other factors

I tried that way but the grid fitted the table object. At the end, I obtain the same effect of my first screenshot. I think the problem is that the table is not able to adapt itself to its content.

oh that's too bad...i admit i hadn't used uitable much in newer versions...I just tested on my matlab and find the same thing. well, that's frustrating...i'll post another answer, though it is cumbersome.
