visual studio - SSRS - Space / Margin between header and tablix in content area on subsequent page -

okay, know question hard digest.

so hope attached picture make more sense of question.

basically want maintain space between header , tablix after first page.

i use bottom border header , user don't want see table , header glued together.

tried put empty textbox (hidden) not working can't repeat textbox on subsequent page.

it looks though have gap between top of report body section , top of tablix - lead gap on first page, not repeated on subsequent pages.

if move tablix there no gap between , top of report body section, should resolve problem.
