I have the following table:
|--------------------+-----+-----+-----+-----+-----+-----|
| Image quality      |  HD | MP4 | STD |  HD | MP4 | STD |
|--------------------+-----+-----+-----+-----+-----+-----|
| NP-FV30 (supplied) |  90 | 100 |  95 |  45 |  50 |  45 |
| NP-FV50            | 170 | 190 | 180 |  85 |  95 |  90 |
| NP-FV70            | 355 | 395 | 375 | 175 | 195 | 185 |
| NP-FV100           | 710 | 785 | 745 | 355 | 390 | 370 |
|--------------------+-----+-----+-----+-----+-----+-----|

But I like to put the following headers above it:
|--------------------+-----------------------------------|
|                    | Recording Time                    |
|--------------------+-----------------------------------|
|--------------------+-----------------+-----------------|
| Battery pack       | Continuous      | Typical         |
|--------------------+-----------------+-----------------|

So I would get:
|--------------------+-----------------------------------|
|                    | Recording Time                    |
|--------------------+-----------------------------------|
|--------------------+-----------------+-----------------|
| Battery pack       | Continuous      | Typical         |
|--------------------+-----------------+-----------------|
|--------------------+-----+-----+-----+-----+-----+-----|
| Image quality      |  HD | MP4 | STD |  HD | MP4 | STD |
|--------------------+-----+-----+-----+-----+-----+-----|
| NP-FV30 (supplied) |  90 | 100 |  95 |  45 |  50 |  45 |
| NP-FV50            | 170 | 190 | 180 |  85 |  95 |  90 |
| NP-FV70            | 355 | 395 | 375 | 175 | 195 | 185 |
| NP-FV100           | 710 | 785 | 745 | 355 | 390 | 370 |
|--------------------+-----+-----+-----+-----+-----+-----|

Would that be possible?
