整个关键在于：row.rowIndex巧好等于table.tBodies[0].row[index]这里的行索引数+1!!!

注意： 

1，table.tBodies[0].row[index]代表实际的行。这里的index指的是当前表格试图的从0开始的索引号。

tableObject.deleteRow(index)

Value Description
index An integer that specifies the position of the row to delete (starts at 0). The value of -1 can also be used; which result in that the last row will be deleted.

2，row.rowIndex：

The rowIndex property returns the position of a row in the rows collection of a table.
