height of textfield in List no consist with outer's one

[abcg5]

I set some data in detail band.

the column 2, 3 is textfields in list component, other is out of list.(different datasets)

the problem is apparent. 

I want the textfeilds in list will meet the height of row.

But I don't know how to set the attributions of textfeilds and list.

I set the Strecth Type, but it didn't work well.

Anyone could teach me how to let the it go well.

Any one could answer it?
Or jasper report couldn't do it?

Finally, i resolve this problem by the return value of subreport.

But i feel this is a stupid answer.

Because of it will call a subreport with in each row data to only get the other information.

The subrpeort without other functions.
