Grouping table rows and page breaks

Question

I have a relatively long table. Each record has six rows. So an item with an identifier of 16 has <tr-16-1><tr-16-2>.....<tr-16-6>, identifier 25 would be <tr-25-1><tr-25-2>.....<tr-25-6>, etc.

I would like the page breaks to not split any grouping of the six rows. So if <tr-25-6> would continue on a new page, I would like all <tr-25's> to break with it.

I can easily attach a class to all six rows if that would help. Can anyone please point me in the right direction on how to do this? Thanks so much for your help.

Answer 1

A possibility is grouping all the rows that are referring to the same record inside a single tbody, so you have more tbody each one containing 6 rows (it's perfectly fine and seems to be logical as an atomic group), then add this rule for media print

@media print {
    tbody {
        page-break-inside: avoid;
    }
}

In this way a page break inside a tbody will be avoided.
Unfortunately page-break-inside is supported on every modern browser except Firefox (Bug #132035)

Answer 2

I would give this a shot:

@media print {
    tr, td, th { page-break-inside:avoid }
}
