Table does't work properly in Link Segment

The cross section is a rectangle. Its height is associated with a variable H.

I created a table htab1, the shape of it is like this

I created 2 segments:

Segment1 use link segment, and its vartiable H was associated with htab1;

Segment2 use regular segment, and its vartiable H was associated with htab1 too.

 

The resulting model of Segment1 has steped shape´╝î which is wrong

while the resulting model of Segment2 has smoothed shape, which is correct
