/**
 * A Column used to render text. Supports tooltips. Supports wrapping with a css style. Supports truncation.
 *
 * If truncation is enabled, and if the text doesn't fit in the parent element, it is truncated.
 *
 * There are two types of truncation. You can specify a length in characters, or if you don't, overflow
 * will be detected and truncated via CSS 'text-overflow: ellipse'.
 *
 * Truncation can also be disabled.
 *
 * When text is truncated, the full text will be rendered in a tooltip, unless a different tooltip is manually
 * configured. Configure a manual tooltip by overriding getTooltip().
 *
 * @param <T>
 *            Table row data type.
