Question

使用iTextSharp运行报告时，我们可以将所有子类别保持在一起，定义单独的PdfpTable和KeepTogether = True

这对于不太可能超过整页的子类别非常有效。

如果主要类别不适合当前页面，是否有办法将主要类别移动到下一页？

这就是我们得到的

费用从最后一个主要类别的末尾开始，但子类别都在下一页上

这是如何创建它们的片段......

由于

 vTable.AddCell(AddNewTextCell(True, "REVENUE", 15, ReportFontSize, False))
        vTable.AddCell(Spacer_Cell(10, 15))

Answer 1

比我想象的更简单 - 只需为每个标题添加subTables

开始一个表

 Dim vRevenueTable As New PdfPTable(15)
        vRevenueTable.KeepTogether = True

        vRevenueTable.AddCell(AddNewTextCell(True, "REVENUE", 15, ReportFontSize, False))
        vRevenueTable.AddCell(Spacer_Cell(10, 15))
        For Each Row As DataRow In RevenueData
            Dim vInnerTable As New PdfPTable(15)
            vInnerTable.KeepTogether = True

....该表的结尾

vInnerTable.AddCell(AddNewCurrencyCell(RT, True, True, ReportFontSize, False))
            vRevenueTable.AddCell(NoSplitTable(vInnerTable, 15))

            'Remove the DictionaryValues
            For i As Integer = 0 To 12
                DicSubs(i) = 0
            Next
            RT = 0
        Next
        vRevenueTable.AddCell(Spacer_Cell(10, 15))
        'Add in the Totals For Revenue
        vRevenueTable.AddCell(AddNewTextCell(True, "TOTAL REVENUE", 2, ReportFontSize, False))
        For i As Integer = 0 To 12
            vRevenueTable.AddCell(AddNewCurrencyCell(DicRevenue.Item(i), True, True, ReportFontSize, False))
        Next
        GT = 0
        RT = 0
        vRevenueTable.AddCell(Spacer_Cell(20, 15))

        vTable.AddCell(NoSplitTable(vRevenueTable, 15))

Answer 2

除了使用keeptogether-tables之外，您还可以通过调用来强制分页 Document.NewPage（）或用Chapters和Sections包装表而不是创建一个大表容器。（4.1.6.0）
