How can I use table headers only without using rows.

Question

how can I use table headers only, without using rows and without leaving the space.
If anyone could say me how to paste the pic in this questions, I would have shown it.
The flow of view is in this way
{Table header(table on top of table)
column header1___|| column header2__ || column header3__ ||}
<b>Here is the blank space I am getting, How to avoid this space?this space is of one table row height</b>
{Contents column1 || Contents column2 || Contents column3 || (This is of other table below the uper table)}
I am using scroll for the content part of table only.
So I am using two tables.
I am using NW04.

Answer 1

I did the possibles you explained, but couldn't get rid off the space.
Any other solutions?
I am keeping the header static and the content columns scrollable.
I have used two tables one to display header above and the other to display only the contents.
I have put the contents table in scroll container.
And the header table in transperent container.
