如何利用DOM解析表格里面的内容?
我知道可以用DOM创建表格，那么如何解析现有表格里面的内容呢？将里面的字符返回数组，让程序进一步处理。

例如这样的表格：

HTML code

<table><tr>    <td>String1_1</td>    <td>String1_2</td>    <td>String1_3</td></tr><tr>    <td>String2_1</td>    <td>String2_2</td>    <td>String2_3</td></tr><tr>    <td>String3_1</td>    <td>String3_2</td>    <td>String3_3</td></tr><tr>    <td>String4_1</td>    <td colspan="2">String4_2</td>  </tr></table>

[解决办法]
object.rows
object.rows(vIndex[,iSubIndex])

返回数组表格所有行 Array of tr objects.

object.cells
object.cells(vIndex [,iSubIndex])

返回数组行的所有表格 Array of td and th elements contained by the object. If the object is a tr, the array contains elements only in that table row. If the object is a table, the array contains all elements in the table.
