Aligning text in iText in a single row
提问by Karlovsky120
What is the best way to create a row of text that will have two elements aligned to an imaginary line? Like this (four rows given to illustrate the point better):
创建一行文本的最佳方法是什么，其中两个元素与一条假想线对齐？像这样（给出四行以更好地说明这一点）：
1. some random text
34. some more random text
764. here's even more random text
4594. it just never ends
Imaginary line would go trough the dots, or the space after them. The numbers have right alignment, and the text has left alignment.
假想线将穿过点，或它们之后的空间。数字右对齐，文本左对齐。
I do not want to use a list because elements may not be in order, and it has certain limitation with setting the line spacing.
我不想使用列表，因为元素可能不按顺序排列，并且在设置行距方面有一定的限制。

You can use a PdfPTable with 2 columns, the first right aligned and the last left aligned. Then set the designer padding on the cells content. For example:
您可以使用具有 2 列的 PdfPTable，第一列右对齐，最后一列左对齐。然后在单元格内容上设置设计器填充。例如：
PdfPTable tbl = new PdfPTable(2);
PdfPCell cell = new PdfPCell(new Phrase("1."));
cell.setHorizontalAlignment(Element.ALIGN_RIGHT);
cell.disableBorderSide(Rectangle.BOX);
tbl.addCell(cell);
cell = new PdfPCell(new Phrase("some random text"));
cell.disableBorderSide(Rectangle.BOX);
tbl.addCell(cell);
cell = new PdfPCell(new Phrase("34."));
cell.disableBorderSide(Rectangle.BOX);
cell.setHorizontalAlignment(Element.ALIGN_RIGHT);
tbl.addCell(cell);
cell = new PdfPCell(new Phrase("some more random text"));
cell.disableBorderSide(Rectangle.BOX);
tbl.addCell(cell);
You can see that cell border are disabled (disableBorderSidemethod).
You can also adjust the minimum height of cells using setMinimumHeightmethod.
您可以看到单元格边框已禁用（disableBorderSide方法）。您还可以使用setMinimumHeight方法调整单元格的最小高度。
