ITextSharp表格单元格Colspan

itext c#

taiko · 技术社区 · 6 年前

我有一张桌子,所有东西都印好了,但只有一个问题。即使我将列设置正确,它也只打印出每列的默认宽度…

在这种情况下,我尝试设置一个float[](在实例化表时),以查看是否可以设置每列的宽度(即使cell对象的colspan应该已经处理了它),但即使如此,它也没有改变。以前,我有列数的整数,但是结果是一样的。我需要澄清这一点,因为文档的一部分已经过时了。

doc.Add(NewTable(new float[4] { 0, 0, 0, 0 }, new float[3] { 1, 5, 5 }, 250, 0, -1, 200, 150,
                                        new List<Cell>() {
                                            NewCell(new Paragraph("N.Âº do Auto:").SetFont(FontBold), ColorGray, new SolidBorder(1),1, 1, 2.5f, HorizontalAlignment.LEFT,VerticalAlignment.MIDDLE),
                                            NewCell(new Paragraph("fdgdfgdfg").SetFont(FontRegular), ColorGray, new SolidBorder(1),1, 2, 2.5f, HorizontalAlignment.LEFT,VerticalAlignment.MIDDLE),
                                            NewCell(new Paragraph("Data:").SetFont(FontBold), ColorGray, Border.NO_BORDER,1, 1, 2.5f, HorizontalAlignment.LEFT,VerticalAlignment.MIDDLE),
                                            NewCell(new Paragraph(DateTime.Now.ToString("dd/MM/yyyy")).SetFont(FontRegular), ColorGray, Border.NO_BORDER,1, 2, 2.5f, HorizontalAlignment.LEFT,VerticalAlignment.MIDDLE),
                                            NewCell(new Paragraph("Morada:").SetFont(FontBold), ColorGray, Border.NO_BORDER,1, 1, 2.5f, HorizontalAlignment.LEFT,VerticalAlignment.MIDDLE),
                                            NewCell(new Paragraph("fdgdfgdfg").SetFont(FontRegular), ColorGray, Border.NO_BORDER,1, 2, 2.5f, HorizontalAlignment.LEFT,VerticalAlignment.MIDDLE)
                                        }));

你通过 float[] pointColumnWidths 但它在任何地方都没有用过吗?

试试这个:

private static Table NewTable(float[] paddings, float[] pointColumnWidths, float width, int rowStart, int rowEnd, float horizontalPosition, float verticalPosition, List<Cell> cells)
{
    Table table = new Table(pointColumnWidths);

    table.SetPaddings(paddings[0], paddings[1], paddings[2], paddings[3]);

    foreach (Cell cell in cells)
        table.AddCell(cell);

    table.SetFixedPosition(horizontalPosition, verticalPosition, width);

    return table;
}
