5.7:H305106 Provide abbreviations for header labels.

Improper design

There was no usage of abbr for long labeling title.

Improper design:

  <TABLE border="1" summary="the rain percentage increased in the main cities of Taiwan, 
  therefore the in-far red level is just right">
  <CAPTION>
  Weather and in-far red level in the main cities of Taiwan.
  </CAPTION>
  <TR>
  <TH>main cities</TH>
  <TH>rain percentage</TH>
  <TH>In-far red level</TH>
  </TR>
  <TR>
  <TD>taipei</TD>
  <TD>100%</TD>
  <TD>good</TD>
  </TR>
  <TR>
  <TD>tai-chong</TD>
  <TD>60%</TD>
  <TD>good</TD>
  </TR>
  <TR>
  <TD>kuo-shung</TD>
  <TD>50%</TD>
  <TD>good</TD>
  </TR>
  </TABLE>

End of example
