jQuery Grid Plugin - jqGrid

Hi,

I would like to arrange the cells within a row differently.
Right now, the arrangement is as follows:

| Column_1 | Column_2 | Column_3 | Column_4 | Column_5 | Column_6 |
|     Cell_1    |     Cell_2    |    Cell_3    |     Cell_4    |     Cell_5    |     Cell_6    |

I would like to change the arrangement this way:

| Column_1 | Column_2 | Column_3 | * unnecessary
| Column_4 | Column_5 | Column_6 | * unnecessary

|    Cell_1    |    Cell_2     |    Cell_3    | * required
|    Cell_4    |    Cell_5     |    Cell_6    | * required

or this:

| Column_1 | Column_3 | Column_5 | * unnecessary
| Column_2 | Column_4 | Column_6 | * unnecessary

|    Cell_1    |    Cell_3     |    Cell_5     | * required
|    Cell_2    |    Cell_4     |    Cell_6     | * required

Is there any way to arrange the cells in this way, that these are distributed on two lines?

Thank You.
