Setting Up an Array with Fields

There may be a time when you need to create an "array" in the middle of a sentence. For instance, you may need to have a 3 x 3 "mini table" within a sentence. Using an actual table can be unwieldy, particularly if you literally want the array in-line within your sentence.

If you have such a special need, try this out:

1. Determine how many columns you want in your array.
2. Determine the elements to appear in each cell of the array.
3. Position the insertion pointer where you want the array to appear.
4. Press Ctrl+F9 to insert a pair of field braces.
5. Enter your field so that it appears as shown here:

{ EQ \a \ac \co3 (One,Two,Three,Four,Five,Six,Seven,Eight) }

When putting together your field, the \a switch indicates you are creating an array. The \ac switch indicates you want the information in each cell centered (you can also use \al for left alignment or \ar for right alignment). The \co3 switch indicates you want three columns in this array; you can (and should) change the number in the switch to reflect the number of actual columns you want in the array. Finally, the information within the parentheses represents the text to appear in each cell of the array, top to bottom and left to right. As shown in this example, the resulting array will be three columns by three rows.

You can also add some spacing switches to the field, if desired. For instance, if you wanted four points of space both vertically and horizontally between the array cells, you could add \vs4 \hs4 to the field.

It is hard to describe the effects of setting up an array. The best way to understand it is simply to try it. You may very well find many instances when you can use arrays in your own documents.
