想知道是否有办法生成具有分隔类别的HTML表格

I was wondering if there was a way to generate an HTML table where there is a category (via the th tag) and separated boards like below (ideally with a td tag)?

|--------------------------------------|
| Category 1 | Category 2 | Category 3 |
|--------------------------------------|
|    Board1  |    Board1  |   Board1   |
|--------------------------------------|
|    Board2  |    Board2  |   Board2   |
|--------------------------------------|
|    Board3  |    Board3  |   Board3   |
|--------------------------------------|
|    Board4  |    Board4  |   Board4   |
|--------------------------------------|
|    Board5  |    Board5  |   Board5   |
|--------------------------------------|
|    Board6  |    Board6  |   Board6   |
|--------------------------------------|

I'm going to be automatically generating this table via PHP+MySQL. I have the category names printing out perfectly, but I'm having difficulties with the boards being put in the correct categories. (if someone can help me out with this one too, that'd be awesome.)
