Fixed header covers row

auchha08

Hi,
(Forgive if the following description includes poor terminology, I am not a html expert)
I have implemented fixed headers on a table and it works well.
However each row is an anchor for a link.
When I navigate to a row in the table from another page, the correct row is selected, however the row is covered by the fixed header.

Is there any way to "shunt" the row down the page so its clearly displayed?

FYI each row starts with the id attached e.g. <tr id=x123.....
I tried using target: before in the css file but so far that seem to want to add a cell at the start of the row and misses up the column alignment

Any feedback appreciated
