 <tr><th>Regex</th><td>If you enter a regular expression, the first occurrence of the expression within the selection in each row of the rectangular selection is matched. Use the <strong>match case</strong> box to indicate whether to use case-sensitive matching. If <strong>Skip unmatched lines</strong> is checked and the regular expression box is not empty, rows in which the regular expression does not match are ignored; the formula is not evaluated, nor is a tab or any space padding added to the selection in the row to account for the new column.</td></tr>
 <tr><th>Thousands separator</th><td>Select a <strong>Thousands separator</strong> option (<strong>None</strong>, <strong>Comma</strong>/<strong>Period</strong>, <strong>Apostrophe</strong> or <strong>Blank</strong>) to control how numeric results are formatted.</td></tr>
 <tr><th>Decimal places</th><td>Choose the number of decimal places (0-16) to which to round results. If <strong>Suppress trailing zeros</strong> is checked, zeros at the end of the decimal portion of numbers are omitted; if this box is not checked, exactly the number of decimal places selected are included.</td></tr>
-<tr><th>Format as time</th><td>If you are calculating are times which you want shown as <em>days</em>:<em>hours</em>:<em>minutes</em>:<em>seconds</em>, check the <strong>Time format</strong> box. Check <strong>Unit is minutes</strong> if the times you are using do not include seconds, and check or uncheck <strong>Show days</strong> according to whether or not you want values of 24 hours or more to be shown with the number of days followed by a colon at the beginning of the result. (Note: If your times are minutes and seconds and you don't want hours shown for values of 60 minutes or more, checking both <strong>Unit is minutes</strong> and <strong>Show days</strong> will accomplish this, since calculating minutes and seconds without days or hours is identical to calculating hours and minutes without days or seconds.)</td></tr>
