In this fix most of the "striped" tables in the javadoc of java.desktop
module are updated:
- New attribute scope="col/"row" was added to all headers.
- Optional tags like </td>, </tr> were removed.
- Most of custom table styles like "style=text-align:center" were
removed, so all tables now unified.
- In a few places the """ was replaced by ", because " is widely
used in our docs anyway.
Some unchanged tables will be updated later(html files inside doc-files
folder, and some tables which are used for layout).
