我有一个要转换成 PDF 的大表格。它的前 1/6 看起来像这样：

然而，输入字段的数量从每节 1 到 20 不等，我需要能够智能地使该文档分页。我的计划是最初逐张绘制表格，并通过抓取所有先前表格中的行数来管理 Y 坐标。这行得通，但是当我进入分页符时就崩溃了，我开始需要一些半复杂的逻辑来使其工作，而且这种逻辑随着每个附加表的添加而变得越来越混乱。
我的第二个计划是在 PDF 中重现 HTML 文档的表格结构，我成功地做到了……
private void DrawPDF()
{
Document tDoc = new Document();
MigraDoc.DocumentObjectModel.Style style = tDoc.Styles["Normal"];
style.Font.Name = tPdfFont;
style.Font.Size = 10;
Section tSec = tDoc.AddSection();
MigraDoc.DocumentObjectModel.Tables.Table masterTable = new MigraDoc.DocumentObjectModel.Tables.Table();
masterTable = tSec.AddTable();
masterTable.Borders.Visible = false;
Column leftColumn = masterTable.AddColumn("365pt");
Column spacer = masterTable.AddColumn("10pt");
Column rightColumn = masterTable.AddColumn("365pt");
Row tFS = masterTable.AddRow();
Cell tCell = tFS.Cells[0];
//
// Farm Assets Column
//
{
MigraDoc.DocumentObjectModel.Tables.Table tAssetsTable = new MigraDoc.DocumentObjectModel.Tables.Table();
tAssetsTable.Borders.Visible = false;
Column tColumn = tAssetsTable.AddColumn("365pt");
tCell.Elements.Add(tAssetsTable);
//
// Current Farm Assets
//
for (int i = 0; i < 10; i++) // Drawn 10 times to force it to draw over the 1st page.
{
Section thisSection = tDoc.AddSection();
Row tAssetsRow = tAssetsTable.AddRow();
Cell tAssetsCell = tAssetsRow.Cells[0];
MigraDoc.DocumentObjectModel.Tables.Table table = new MigraDoc.DocumentObjectModel.Tables.Table();
table = thisSection.AddTable();
table.Borders.Width = 0.2;
table.Rows.LeftIndent = 0;
Column columnData = table.AddColumn("295pt");
columnData.Borders.Left.Visible = false;
Column columnValue = table.AddColumn("70pt");
Row rowA = table.AddRow();
rowA.Shading.Color = Color.FromRgbColor((byte)255, Color.Parse("0xa2a2d2"));
rowA.Cells[0].AddParagraph("CURRENT FARM ASSETS");
rowA.Cells[1].AddParagraph("$ Value");
rowA.Cells[1].Format.Alignment = ParagraphAlignment.Right;
Row row1 = table.AddRow();
row1.Borders.Bottom.Visible = false;
row1.Cells[0].AddParagraph("Cash: Savings: ($" + MP.FormFinancialStatement.CurrentStaticAssets.Savings + ") Checking: ($" + MP.FormFinancialStatement.CurrentStaticAssets.Checking + ")");
row1.Cells[1].AddParagraph(MP.FormFinancialStatement.CurrentStaticAssets.CashTotal);
row1.Cells[1].Format.Alignment = ParagraphAlignment.Right;
Row row2 = table.AddRow();
row2.Borders.Bottom.Visible = false;
row2.Cells[0].AddParagraph("Invest: Time Cret $" + MP.FormFinancialStatement.CurrentStaticAssets.TimeCret + " Other: $" + MP.FormFinancialStatement.CurrentStaticAssets.OtherInvestments + "");
row2.Cells[1].AddParagraph(MP.FormFinancialStatement.CurrentStaticAssets.InvestTotal);
row2.Cells[1].Format.Alignment = ParagraphAlignment.Right;
Row row3 = table.AddRow();
row3.Borders.Bottom.Visible = false;
row3.Cells[0].AddParagraph("Replacement Account");
row3.Cells[1].AddParagraph(MP.FormFinancialStatement.CurrentStaticAssets.ReplacementAccount);
row3.Cells[1].Format.Alignment = ParagraphAlignment.Right;
Row row4 = table.AddRow();
row4.Cells[0].AddParagraph("Accouts and Notes Recievable");
row4.Cells[1].AddParagraph(MP.FormFinancialStatement.CurrentStaticAssets.AccountsNotesReceivable);
row4.Cells[1].Format.Alignment = ParagraphAlignment.Right;
MigraDoc.DocumentObjectModel.Tables.Table clone = (MigraDoc.DocumentObjectModel.Tables.Table)table.Clone();
tAssetsCell.Elements.Add(clone);
}
}
MigraDoc.Rendering.DocumentRenderer docRenderer = new DocumentRenderer(tDoc);
docRenderer.PrepareDocument();
docRenderer.RenderObject(gfx, 30, 85, "740pt", masterTable);
}
但是，这实际上并没有正确地打破页面。我尝试分割每个单独的表，希望这会产生分页魔法，但事实并非如此。
我如何构建它以允许良好的分页符？
