How to show multiline text in a table cell

You want to use the CSS white-space:pre applied to the appropriate <td>. To do this to all table cells, for example:

td { white-space:pre }

Alternatively, if you can change your markup, you can use a <pre> tag around your content. By default web browsers use their user-agent stylesheet to apply the same white-space:pre rule to this element.

The PRE element tells visual user agents that the enclosed text is "preformatted". When handling preformatted text, visual user agents:

• May leave white space intact.
• May render text with a fixed-pitch font.
• May disable automatic word wrap.
• Must not disable bidirectional processing.

style="white-space:pre-wrap; word-wrap:break-word"

This would solve the issue of new line. pre tag would add additional CSS than required.
