# 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 ## Proper demonstration Use abbr for excessive long titles. Proper example:
      <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 abbr="city">main cities</TH>
      <TH abbr="rain">rain percentage</TH>
      <TH abbr="in-far red">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>
