想用proc template修改结果输出格式，但是总是出错。如下：

170  proc template;
171  define style mystyle;
172  parent = Styles.RTF;
173  replace fonts /
174  'TitleFont' = ("Times Roman",13pt,Bold) /* Titles from TITLE statements */
175  'TitleFont2' = ("Times Roman",12pt,Bold Italic) /* Procedure titles ("The _____
176  Procedure")*/
177  'StrongFont' = ("Times Roman",10pt,Bold)
178  'EmphasisFont' = ("Times Roman",10pt,Italic)
179  'headingEmphasisFont' = ("Times Roman",11pt,Bold Italic)
180  'headingFont' = ("Times Roman",10pt) /* Table column and row headings */
181  'docFont' = ("Times Roman",10pt) /* Data in table cells */
182  'footFont' = ("Times Roman",10pt) /* Footnotes from FOOTNOTE statements */
183  'FixedEmphasisFont' = ("Courier",9pt,Italic)

192  'bg' = white; /* page background color */;
193  replace Body from Document /

200  rules = groups /* internal borders: none, all, cols, rows, groups */
201  cellpadding = 5pt /* the space between table cell contents and the cell border */
202  cellspacing = 0pt /* the space between table cells, allows background to show */
203  borderwidth = 0.5pt /* the width of the borders and rules */;
204  style SystemFooter from SystemFooter /
