Code:
<?php
/**
 * Split rows to columns.
 * @version 1.0
 * @author Mikhail Kharitonov <mvh@list.ru>
 *
 * Example 1:
 * <table>
 *     {$foo=0}
 *     {foreach array(1,2,3,4,5,6,7,8,9,10) as $number}
 *         {columnSeparator size=5 total=$number@total iteration=$number@iteration}
 *             </table><table>
 *             {* Code in this block will be executed only when condition is true *}
 *             {$foo=$foo+1}
 *         {/columnSeparator}
 *
 *         <tr>{$number}</tr>
 *     {/foreach}
 * </table>
 * Foo is {$foo}
 *
 * Output:
 * <table>
 *     <tr>1</tr>
 *     <tr>2</tr>
 *     <tr>3</tr>
 *     <tr>4</tr>
 *     <tr>5</tr>
 * </table><table>
 *     <tr>6</tr>
 *     <tr>7</tr>
 *     <tr>8</tr>
 *     <tr>9</tr>
 *     <tr>10</tr>
 * </table>
 * Foo is 1
 * -----------------------------------------------------------
 * Example 2:
 * <table>
 *     {foreach array(1,2,3,4,5,6,7,8,9,10) as $number}
 *         {columnSeparator size='50%' groupSize=3 total=$number@total iteration=$number@iteration}
 *             </table><table>
 *         {/columnSeparator}
 *
 *         <tr>{$number}</tr>
 *     {/foreach}
 * </table>
 *
 * Output:
 * <table>
 *     <tr>1</tr>
 *     <tr>2</tr>
 *     <tr>3</tr>
 *     <tr>4</tr>
 *     <tr>5</tr>
 *     <tr>6</tr>
 * </table><table>
 *     <tr>7</tr>
 *     <tr>8</tr>
 *     <tr>9</tr>
 *     <tr>10</tr>
 * </table>
 * -----------------------------------------------------------
 * Example 3 (nested columns):
 * <div>
 * <table>
 * {foreach array(1,2,3,4,5,6,7,8,9,10) as $number}
 *     {columnSeparator size=2 total=$number@total iteration=$number@iteration}
 *         </table>
 *         {columnSeparator size=6 total=$number@total iteration=$number@iteration}
 *             </div>
 *             <div>
 *         {/columnSeparator}
 *         <table>
 *     {/columnSeparator}
 *
 *     <tr>{$number}</tr>
 * {/foreach}
 * </table>
 * </div>
 *
 * Output:
 * <div>
 *     <table>
 *         <tr>1</tr>
 *         <tr>2</tr>
 *     </table>
 *     <table>
 *         <tr>3</tr>
 *         <tr>4</tr>
 *     </table>
 *     <table>
 *         <tr>5</tr>
 *         <tr>6</tr>
 *     </table>
 * </div>
 * <div>
 *     <table>
 *         <tr>7</tr>
 *         <tr>8</tr>
 *     </table>
 *     <table>
 *         <tr>9</tr>
 *         <tr>10</tr>
 *     </table>
 * </div>
