iText 7 table 每页最后一行底部有边框
iText 7 table with border bottom on last row of each page
我正在使用 iText 7 在 PDF 文件中创建 table。
我的 table 必须只有垂直边框（每列的左侧和右侧）并且在每页的第一行也有拓扑边框
并且在每页的最后一行也是底部边框。
在每一行中，只有一列可以在两行上“跨行”（最多）。
我已经成功地创建了 table 并在每页上重复 header 但在每页的最后一行我无法绘制底部边框。
可以通过多种方式解决问题。
我使用函数 GetCell 获取一个单元格 object，然后像这样添加到 table
var stream = new MemoryStream();
var writer = new PdfWriter(stream);
var pdf = new PdfDocument(writer);
pdf.SetDefaultPageSize(PageSize.A4.Rotate());
var document = new Document(pdf);
iText.Layout.Element.Table table;
...HEADER
table.AddHeaderCell(GetCell(1, 1, "V", dgv.Columns[i].HeaderText, "{0}", TextAlignment.CENTER, VerticalAlignment.TOP));
....AddHeaderCell for all columns
....init cycle
table.AddCell(GetCell(1, 1, "F", mystring, TextAlignment.CENTER, VerticalAlignment.TOP).SetBorder(null));
...ending cycle
document.Add(table);
document.close;
.....
然后遍历 table 中的所有单元格并将左右边框应用于单元格。
int numrows= table.GetNumberOfRows();
int numcols= table.GetNumberOfColumns();
for (int irow = 0; irow < numrows; irow++)
{
for (int icol = 0; icol < numcols; icol++)
{
try
{
Cell mycell = table.GetCell(irow,icol);
mycell.SetBorderRight(new SolidBorder(0.5f));
mycell.SetBorderLeft(new SolidBorder(0.5f));
}
catch (NullReferenceException)
{
}
}
}
最大的困难是知道我正在写的行是否是页面上的最后一行，另一个困难是在迭代周期中获取单元格值。
注意事项：
我也可以在 GetCell 函数中应用底部边框，在这种情况下，我应该在这个阶段知道我的行是否是页面中的最后一行。我试过这个但结果不好
添加单元格后，我验证是否有足够的 space 来写另一行。
LayoutResult result = table.CreateRendererSubTree().SetParent(document.GetRenderer()).Layout(
new LayoutContext(new LayoutArea(1, new Rectangle(0, 0, 400, 1e4f))));
LayoutArea currentArea = document.GetRenderer().GetCurrentArea();
Rectangle rectangle = currentArea.GetBBox();
float verticalPosition = rectangle.GetHeight();
float docBottom = rectangle.GetBottom();
float TableHeight = result.GetOccupiedArea().GetBBox().GetHeight();
if (verticalPosition - TableHeight <= docBottom)
{
// document.Add(new AreaBreak(AreaBreakType.NEXT_PAGE));
//Debug.Print("........................................Last Row splitted");
};
private static Cell GetCell(int cm, int rowspan, string ItsHeader, string mytext, TextAlignment mytextalign,
VerticalAlignment myvertalign) {
Cell cell = new Cell(rowspan, cm);
Paragraph p;
if (ItsHeader == "V") {
cell.SetBackgroundColor(iText.Kernel.Colors.ColorConstants.LIGHT_GRAY);
cell.SetTextAlignment(mytextalign);
p = new Paragraph(String.Format("{0}", mytext)).SetFontSize(10);
cell.Add(p);
} else {
if (myvertalign == VerticalAlignment.MIDDLE) {
Div d = new Div();
d.SetVerticalAlignment(VerticalAlignment.MIDDLE);
p = new Paragraph(String.Format("{0}", mytext)).SetFontSize(8);
p.SetTextAlignment(mytextalign);
d.Add(p);
cell.Add(d);
} else {
cell.SetBackgroundColor(iText.Kernel.Colors.ColorConstants.WHITE);
p = new Paragraph(String.Format("{0}", mytext)).SetFontSize(8);
p.SetTextAlignment(mytextalign);
p.SetMultipliedLeading(1.5f);
p.SetMarginTop(0);
cell.Add(p);
}
}
return cell;
}
感谢您的时间和建议。
我会得到这样的东西
Example
这样解决了。
我结合了一些给我带来问题的事情。
- Table 每页重复页眉。
- Table 有边框。
- 只有左右边框的单元格
- 最后一页最后一行的总计
- 每页第一行打印 2 列值
唯一的条件是定义一个变量，用于存储页面内 table 的最大高度（对我来说是水平方向）。如果超过此高度，则会生成分页符。
谢谢你的时间。

iText.Layout.Element.Table table;

table.AddHeaderCell(GetCell(1, 1, "V", dgv.Columns[i].HeaderText, "{0}", TextAlignment.CENTER, VerticalAlignment.TOP));

然后遍历 table 中的所有单元格并将左右边框应用于单元格。

最大的困难是知道我正在写的行是否是页面上的最后一行，另一个困难是在迭代周期中获取单元格值。
注意事项：
我也可以在 GetCell 函数中应用底部边框，在这种情况下，我应该在这个阶段知道我的行是否是页面中的最后一行。我试过这个但结果不好 添加单元格后，我验证是否有足够的 space 来写另一行。
LayoutResult result = table.CreateRendererSubTree().SetParent(document.GetRenderer()).Layout(
new LayoutContext(new LayoutArea(1, new Rectangle(0, 0, 400, 1e4f))));
LayoutArea currentArea = document.GetRenderer().GetCurrentArea();
Rectangle rectangle = currentArea.GetBBox();
float verticalPosition = rectangle.GetHeight();
float docBottom = rectangle.GetBottom();
float TableHeight = result.GetOccupiedArea().GetBBox().GetHeight();
if (verticalPosition - TableHeight <= docBottom)
{
// document.Add(new AreaBreak(AreaBreakType.NEXT_PAGE));
//Debug.Print("........................................Last Row splitted");
};

感谢您的时间和建议。
我会得到这样的东西 Example
这样解决了。 我结合了一些给我带来问题的事情。
- Table 每页重复页眉。
- Table 有边框。
- 只有左右边框的单元格
- 最后一页最后一行的总计
- 每页第一行打印 2 列值
唯一的条件是定义一个变量，用于存储页面内 table 的最大高度（对我来说是水平方向）。如果超过此高度，则会生成分页符。 谢谢你的时间。
