#114 responsive fixes for table

[Askadar]

Adressed several responsive issues with tables:

• heading is fixed on mobile, and whole table should fit with footer header and content header. Resize event listener might be necessary for rotating;
• reasoning (why added) takes at least 80% of device width to make it easier to read big blob of text;
• generated table column classes to make styling more robust and allow to rearrange data.
