For running text – not sure about tables – you could:

1. place cursor in paragraph
2. press F8 four times (or triple-click) to select paragraph
   there are lots of other F8 tricks for selecting longer blocks of text, too
3. Ctrl+D, Alt+H, Return to hide the selected paragraph

When you're done, Ctrl+A to select the whole document and then Ctrl+spacebar to clear the local override (hidden text) you've applied. note: clearing all local overrides may spring surprises, depending on how styled the original document is
