Extra character formatting may be set by column (in List) or by cell (in Spread) using this property. Normally you would compute this from the data matrix and so it is easy to pass the required emphasis as a simple numeric matrix, each value being the sum of:

• 1=bold
• 2=italic
• 4=underline
• 8=strikethrough

bold„mat<0  © Bolded negatives
nltEmphasis bold

If you pass a simple vector, it is reshaped across the columns. In this case you might prefer to use character codes to set the emphasis of each column:

nltEmphasis '' '' '' 'bold'

This example will embolden every 4th column in the table. Note that you can pass the emphasis property in the optional left argument to both List and Spread, in which case it only applies to that particular table.
