delete rows not the datas

hello,

I have doubt that how I can delete the rows but not only the datas.

for eg. 

1  A1

2  A2

3  A3

4  A4

5  A5

Now, I delete the rows, I have only the following

1  A1

2  A2

5 A5 

Here the 2 & 3 rows are deleted.

please tell me , how it is possible with shortcuts
