The font used to render the title ($Name) is set via the Maps document setting Map Font but can be overridden at note level by setting $NameFont to a different value.
The alignment of the title is controlled via $NameAlignment. This is separate from the alignment of displayed $Text, with left aligned being the default for both.
A container's title bar does not allow for displaying both $Text and a Table Expression. A table expression is drawn in the same part of the map icon used to display a note's $Text, therefore both cannot be shown in the same map icon. If $TableExpression or $TableHeading are set, $Text will not be displayed. More on container summary display tables.
Be aware that adornments have the option of using a different font for their titles: $AdornmentFont. If the latter is not set at document level, adornment labels default to using $NameFont.
