This is an attempt to render a table with text heights set by the smaller text, but still containing large text (for illustrating the shapes of the letters).

In the table below, observe that the red boxes in the second column still enclose a substantial amount of vertical white space, and the table still contains a lot of extra leading, despite the line-height: 0px in the .uni class style.

The style sheet is replicated below the table for reference.
