Flexible table columns width, rows independent?

Hello,

i have HTML table with 3 rows.
the third row contains in the middle three columns that contains extraordinary long phrasesphrases which cause columns above these long columns to be long too and that looks bad, because above rows contains images so spacing is different.

How can i set the HTML table columns width to be flexible, i mean so the wide third row columns does not influence width of the columns in other rows of the same table?
