Question

我有一张桌子，所有内容都可以打印出来，但是只有一个问题。即使我将列设置正确，它也只是为每列打印出默认宽度...

在这种情况下，我尝试设置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应该已经照顾好了），但是即使如此，它也没有改变。以前，我有整数作为列数，但结果是相同的。由于文档的一部分已过时，我需要对此进行一些澄清。

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.º 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)
                                        }));

您通过了float[] pointColumnWidths，但没有在任何地方使用它。

尝试一下：

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;
}
