tr 行 有几个<tr></tr> 就有几行
td 在表格中我们不提倡说列，td指表格中的每一个单元格, 例如我们来写一个3行3列的表格
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title></title> </head> <body> <table cellpadding="0" cellspacing="0" border="1" width="300"> <tr> <td>1</td> <td>2</td> <td>3</td> </tr> <tr> <td>4</td> <td>5</td> <td>6</td> </tr> <tr> <td>7</td> <td>8</td> <td>9</td> </tr> </table> </body> </html>
可以看出，我们的行有3个，但是我们的单元格有9个
