there is always a offset when print webpage with page-break

I have a table which may have many rows. I want to print it without split each row.

I use page-break-after, page-break-before, page-break-inside to achieve this. However, there will always be some part of next page printed on current page. See my screenshot, the content in the blue box should all print on next page.

My css is :

.table_parent {
  page-break-before:auto;
  page-break-after:auto;
  page-break-inside:avoid;
  position:relative;
}

.table_self tr{
  page-break-before:auto;
  page-break-after:auto;
  page-break-inside:avoid;
  position:relative;
}

Can anybody help ? Thanks very much.
