Why does FlowDocument print tables on half a page?

Question

WPF

Why does FlowDocument print tables on half a page? Moreover, he doesn’t care what size I indicate the columns, he simply cuts them to half the visible part and that’s it.

flowDoc.Blocks.Add(table);

if (printdlg.ShowDialog().GetValueOrDefault())
{
    IDocumentPaginatorSource idpSource = flowDoc;
    printdlg.PrintDocument(idpSource.DocumentPaginator, "Печать отчёта ткани на кладе");
}
