我前二天写了一个工资管理程序，就是可以随时动态打印，在报表生成过程中可自动分析
哪些是应该打的，哪些是不应该的要，并可以根据本列中最长的字符长度自动设置该栏
宽度。可现在改成report machine的了。
请看部分源码：
procedure Tmain.BitBtn3Click(Sender: TObject);
var
i:integer;
begin
table_name:=edit1.Text+combobox1.Text;
title_rep:=edit1.Text+'年'+combobox1.Text+'月份'+'工资发放汇总表'+'（'+combobox3.text+'）';
hz_tmp:='';
for i := 0 to adoquery1.FieldCount - 1do
begin
if (adoquery1.Fields.FieldName<>'ID') and (adoquery1.Fields.FieldName<>'排序') and (adoquery1.Fields.FieldName<>'编制') and (adoquery1.Fields.FieldName<>'姓名') then
if (adoquery1.Fields.FieldName='科室') then
if hz_tmp='' then
hz_tmp:='科室,count(科室) as 人数' else
hz_tmp:=hz_tmp+','+'科室,count(科室) as 人数' else
if hz_tmp='' then
hz_tmp:='sum('+adoquery1.Fields.FieldName+') as '+adoquery1.Fields.FieldName else
hz_tmp:=hz_tmp+','+'sum('+adoquery1.Fields.FieldName+') as '+adoquery1.Fields.FieldName;
end;
with gzdo
begin
close;
sql.Clear;
sql.Add('select '+hz_tmp+' from '+edit1.Text+combobox1.Text);

sql.Add('where 编制='+''''+combobox3.text+'''');
sql.add('group by 科室');
open;
