Такая проблема. Делаю не сложную таблицу.

<table width="760" border="0" cellspacing="0" cellpadding="0"> <tr> <td colspan="17"><img src="images/dot.gif" width="760" height="1"></td> </tr> <tr> <td rowspan="3" class="bot_line"><img src="images/dot.gif" width="100" height="103"></td> <td class="bot_line"><span class="bot_line"><IMG SRC="images/bottom_10.gif" WIDTH=75 HEIGHT=22 ALT="Торговля"></span></td> <td class="bot_line"><span class="bot_line"><IMG SRC="images/bottom_11.gif" WIDTH=8 HEIGHT=22 ALT=""></span></td> <td class="bot_line"><span class="bot_line"><IMG SRC="images/bottom_12.gif" WIDTH=79 HEIGHT=22 ALT="Производство"></span></td> <td class="bot_line"><span class="bot_line"><IMG SRC="images/bottom_13.gif" WIDTH=6 HEIGHT=22 ALT=""></span></td> <td class="bot_line"><span class="bot_line"><IMG SRC="images/bottom_14.gif" WIDTH=64 HEIGHT=22 ALT="Вединг"></span></td> <td class="bot_line"><span class="bot_line"><IMG SRC="images/bottom_15.gif" WIDTH=1 HEIGHT=22 ALT=""></span></td> <td class="bot_line"><span class="bot_line"><IMG SRC="images/bottom_16.gif" WIDTH=133 HEIGHT=22 ALT="Региональные филиалы"></span></td> <td rowspan="3" class="bot_line"><img src="images/dot.gif" width="139" height="1"></td> <td width="60" class="bot_line"><img src="images/dot.gif" width="60" height="1"></td> <td width="14" class="bot_line"><IMG SRC="images/bottom_19.gif" WIDTH=14 HEIGHT=22 ALT="На главную"></td> <td width="7" class="bot_line"><img src="images/dot.gif" width="7" height="1"></td> <td width="13" class="bot_line"><IMG SRC="images/bottom_21.gif" WIDTH=13 HEIGHT=22 ALT="Поиск"></td> <td width="9" class="bot_line"><img src="images/dot.gif" width="9" height="1"></td> <td width="13" class="bot_line"><IMG SRC="images/bottom_23.gif" WIDTH=13 HEIGHT=22 ALT="E-mail"></td> <td width="30" class="bot_line"><img src="images/dot.gif" width="30" height="1"></td> <td width="9" rowspan="3" class="bot_line"><img src="images/dot.gif" width="9" height="1"></td> </tr> <tr> <td colspan="7"><img src="images/dot.gif" width="1" height="15"></td> <td height="17" colspan="7"><img src="images/dot.gif" width="1" height="17"></td> </tr> <tr> <td colspan="7"><table width="366" border="0" cellpadding="0" cellspacing="0"> <tr> <td rowspan="3"><span class="phone"><IMG SRC="images/bottom_28.gif" WIDTH=19 HEIGHT=66 ALT=""></span></td> <td width="121"><span class="phone"><img src="images/dot.gif" width="121" height="1"></span></td> <td rowspan="3" class="phone"><img src="images/dot.gif" width="142" height="1"></td> <td rowspan="3"><img src="images/dot.gif" width="84" height="1"></td> </tr> <tr> <td height="24" class="phone"><img src="images/dot.gif" width="1" height="24"></td> </tr> <tr> <td><span class="phone"><IMG SRC="images/bottom_34.gif" WIDTH=121 HEIGHT=42 ALT="Контактный телефон"></span></td> </tr> </table></td> <td colspan="6"><IMG SRC="images/bottom_32.gif" WIDTH=119 HEIGHT=64 ALT=""></td> <td width="27"><img src="images/dot.gif" width="27" height="1"></td> </tr> </table>

Проблема в том, что вместо прогнозируемых 760 точек, Дримвивер говорит, что ширина таблицы 768 точек. Подскажите, пожалуйста, почему так происходит?

У вас ошибка на 3 пикселя в определении шипины ячейки.
Сумма ячеек справа над большой ячейкой больше на 3 пикселя.
