problem ：

How can I scroll the table's cell to specific position ? How to scroll the cells of a table to a specific position ？I have a table which shows 3 rows (according to height). I have a table that shows 3 That's ok （ According to height ）.what I want is if I click on 1st row than according to table's height the 1st row should scroll and get new position (center) and same for other rows. What I want is if I click on 1 Rows, not according to the height of the table , The first 1 Rows should scroll and get new positions （ center ）, And the same is true for other lines .I tried contenOffset but did not work.. I tried contenOffset But no job ..

EDITED : edit ：

In short some thing like data picker when we select any row in picker the row scrolls to the center. In short , When we select any row in the selector , The data selector scrolls some rows to the center .
