我正在从数据库中读取数据,并使用iTextSharp填充表格。这就是我读数据的方式:
var db = Database.Open("NewDatabase");
var sql =
@"SELECT FullName,
[2017-01-02], [2017-01-03], [2017-01-04],
([2017-01-02] + [2017-01-03] + [2017-01-04]) as 'DatesSum',
[Week1]
FROM [NewTable]";
var data = db.Query(sql);
var columns = data.First().Columns;
var doc = new Document();
PdfWriter.GetInstance(doc, Response.OutputStream);
doc.Open();
PdfPTable table = new PdfPTable(new float[] {30f, 10f, 10f, 10f, 10f, 10f});
foreach(var row in data)
{
foreach(var column in columns)
{
table.AddCell(new Phrase(row[column] != null ? row[column].ToString() : string.Empty));
}
}
doc.Add(table);
doc.Close();
正如您所看到的,我正在使用'foreach'来遍历数据并填充表格。这是我知道填充表格的唯一方法(我对iTextSharp很新)。
我一直在尝试将数据对齐到单元格的中间位置。此外,我想交替行的颜色(每隔一行)。我一直在循环中尝试这样的事情,没有结果:
row[column].HorizontalAlignment = 1;

答案 0 :(得分:3)
设置PdfPCell
HorizontalAlignment
和BackgroundColor
属性。
示例数据:
static readonly int[,] data = new int[,]
{
{ 1, 2 }, { 3, 4 }, { 5, 6 }, { 7, 8 }
};
static readonly int rows = data.GetLength(0);
static readonly int columns = data.GetLength(1);
创建PDF:
var table = new PdfPTable(2)
{
HorizontalAlignment = Element.ALIGN_LEFT,
WidthPercentage = 50
};
var cell = new PdfPCell() {HorizontalAlignment = Element.ALIGN_CENTER};
using (var stream = new MemoryStream())
{
using (var document = new Document())
{
PdfWriter.GetInstance(document, stream);
document.Open();
for (int i = 0; i < rows; ++i)
{
cell.BackgroundColor = i % 2 == 0
? BaseColor.LIGHT_GRAY : BaseColor.WHITE;
for (int j = 0; j < columns; ++j)
{
cell.Phrase = new Phrase(data[i, j].ToString());
table.AddCell(cell);
}
}
document.Add(table);
}
File.WriteAllBytes(OUTPUT, stream.ToArray());
}
输出:
