At this point, the content of the table is complete but it would benefit from the addition of a caption. You have considerable flexibility in associating text with the table, using any or all of the following properties:

• Heading: this is written at the top of the table, centred by default, in a larger font. It repeats across the part-pages if the table spans more than one page wide.
• Subheading: this is written under the heading, with the same alignment, in a smaller font. It is also repeated across part-pages.
• Caption: this is written at the top left of the table, and repeats on every part-page both across and down. It is left-aligned and written in a bold font.
• Footnote: this is written at the very end of the entire table. It defaults to left-aligned and a smaller font.

You can set the font and colour of any of these elements, and the alignment (left, centre, right) of the headers and footnote.

For now, set a standard heading, centred above the table:

nlUse''
nltHeading'Table 1. First Quarter Sales ($000''s)'
nltList salesQ1
View doc„nlClose

Observe what happens when the left and right indents are set to one inch:

nlInit ª nlUse''
nlIndent 72 × 1 1 0
nlAlign 'centre'
nltHeading'Table 1. First Quarter Sales ($000''s)'
nltList salesQ1
View doc„nlClose

Now, try setting each of the first two indents separately to one inch to see what happens to the width and the position of the table and caption.

Completing the Sales Report

By default, a table will occupy the entire frame width, but if you give the all the cell widths explicitly it may be less wide than the frame (in which case it will be aligned using the current paragraph alignment) or some columns may be dropped from the right-hand edge. So, to centre the complete sales report, together with its heading and a footnote:
