It is fixing the child table headers too when we add tableHeadFixer for the parent table

[cis-ankity]

I've created a table which contains a child table inside its td's and when I make the table header fix using the tableHeadFixer it is fixing the table header but it also fixing the child table headers and due to that the child table header not scrolled when we scrolling the parent table.
