body: <p>sample data</p>
  
  <p>01 A AA<br />
  01 A BB<br />
  02 B CC<br />
  03 A DD<br />
  03 A EE<br /></p>
  
  <p>the primary key is first column.
  the first column and second column are common value.
  the last column is personal value.
  i want to merge rows in the first column and second column when the value of the first column is change.</p>
  
  <p>my way is
  first, write in fastreport's code using 'if' command.
  second, use 'groupheader' and add the common columns in the section.</p>
  
  <p>however, the first way have a problem that i don't know how to control index.
  the second way is the groupheader's columns overflow PageFooter when a group end at the end of a page and the other group start at the first of next page.</p>
  
  <p>please..... answer me...TTTTTT!</p>
