以下代碼確實會生成表格和嵌套表格。 但是,嵌套表總是在中間對齊。 我不知道如何正確實現水平對齊。無法在單元格內左對齊嵌套表格
以下方法只是循環遍歷一個列表。 當它是一個簡單的問題時,我將添加一個TextField。 如果它是一個包含多個答案的問題,我將使用複選框和值注入一個嵌套表。
private PdfPTable CreateQuestionTable(RLQuestionRecordList questions)
{
PdfPCell cell;
PdfPTable table = new PdfPTable(2);
//table.SetWidths(new int[]{ 50, 50 });
table.WidthPercentage = 100;
table.SpacingBefore = 20;
table.SpacingAfter = 20;
table.DefaultCell.HorizontalAlignment = Element.ALIGN_LEFT;
foreach (RCQuestionRecord q in questions)
{
//add question to the table
cell = new PdfPCell(new Phrase(q.ssSTQuestion.ssName, _Normal));
cell.Border = Rectangle.NO_BORDER;
cell.Padding = 5.0f;
table.AddCell(cell);
//add answer to the table.
//add generate time we don;t know where the table will be,
//hence textfields will be generated after the pdf has been generated..
if (q.ssSTQuestion.ssListOfAnswers.Length > 0)
{
// we have radiobuttons, so we add a table inside the cell
cell = new PdfPCell();
cell.Border = Rectangle.NO_BORDER;
cell.Padding = 5.0f;
//we cannot align the table to the left in the cell for some weird reason...
cell.HorizontalAlignment = Element.ALIGN_LEFT;
cell.AddElement(CreateCheckboxTable(q));
table.AddCell(cell);
}
else
{
// we have simple textfield, so add that to the cell
cell = new PdfPCell();
cell.Border = Rectangle.NO_BORDER;
cell.Padding = 5.0f;
cell.HorizontalAlignment = Element.ALIGN_LEFT;
//simple textfield
cell.CellEvent = new OOMTextField(string.Format("question_{0}", q.ssSTQuestion.ssQuestionId), q.ssSTQuestion.ssLength, q.ssSTQuestion.ssValue, bf);
table.AddCell(cell);
}
}
return table;
}
這是我想插入到上面的單元格中的嵌套表。
/// <summary>
///
/// </summary>
/// <param name="question"></param>
/// <returns></returns>
private PdfPTable CreateCheckboxTable(RCQuestionRecord question)
{
PdfPCell cell;
int numCells = question.ssSTQuestion.ssListOfAnswers.Length;
PdfPTable table = new PdfPTable(numCells);
float[] widths = new float[numCells];
int currentColumn = 0;
//table.SetWidths(new int[]{ 50, 50 });
foreach (RCAnswerRecord a in question.ssSTQuestion.ssListOfAnswers) {
//checkbox
cell = new PdfPCell(new Phrase(a.ssSTAnswer.ssLabel, _Normal));
cell.Border = Rectangle.NO_BORDER;
cell.Padding = 0.0f;
cell.PaddingLeft = 20.0f;
cell.HorizontalAlignment = Element.ALIGN_LEFT;
cell.VerticalAlignment = Element.ALIGN_CENTER;
cell.CellEvent = new OOMCheckBox(string.Format("question_{0}", question.ssSTQuestion.ssQuestionId), a.ssSTAnswer.ssIsSelected, a.ssSTAnswer.ssLabel, bf);
//checkbox
table.AddCell(cell);
widths[currentColumn++] = 20.0f + bf.GetWidthPoint(a.ssSTAnswer.ssLabel, 11);
}
table.SetTotalWidth(widths);
table.LockedWidth = true;
table.SpacingBefore = 0;
return table;
}
我錯過了將嵌套表完全對齊到單元格左側的內容?
太棒了,謝謝! – Mafti 2014-10-31 07:07:18
