How to prevent line-break in a column of a table cell (not a single cell)?

Question

How can I prevent automatic line breaks in a column of table (not a single cell)?

Answer 1

For completion sake:

#table_id td:nth-child(2)  {white-space: nowrap;}

Is used for applying a style to the 2 column of the table_id table.

This is supported by all major Browsers, IE started supporting this from IE9 onwards.
