Complex column header with several icons

Drujik

Hi,
I know I'm going to write some specific problem (and sorry if it's not the place), but my my head is ripping on the parts
I have a table, that must have the following behavior:
* Header may have subtitle. Subtitle must be on the next line and with different style
* Header must have filter icon (can be shown on hover)
* Header's sort icon must be next to filter icon
Like shown in the attached file.
But when I try to do this, the column width is auto adjusted to the text, not to whole content of header html

Please anyone help!
