如何在同一页pdfbox上创建多个表格？

Question

我想使用pdfbox和boxable创建多个表格(表格如下)。但是表是重叠的，我该怎么解决呢？

for(ProductGroup productGroup: productGroups) {
            BaseTable table = new BaseTable(yStart, yStartNewPage, bottomMargin, tableWidth, margin, doc, page, true, drawContent);
            Row<PDPage> headerRow = table.createRow(15f);
            Cell<PDPage> cell;
            createHeader(headerRow, table);
            Row<PDPage> row;
            for(Article article: productGroup.getArticles()) {
                row = table.createRow(10f);
                cell = row.createCell((100 / 9f) , article.getBranch().replace("\n", "").replace("\r", ""));
                cell.setFont(PDType1Font.HELVETICA);
                cell.setFontSize(fontSize10);
                cell = row.createCell((100 / 9f) , article.getMode().replace("\n", "").replace("\r", ""));
                cell.setFont(PDType1Font.HELVETICA);
                cell.setFontSize(fontSize10);
                cell = row.createCell((100 / 3f) , article.getFeatureText().replace("\n", "").replace("\r", ""));
                cell.setFont(PDType1Font.HELVETICA);
                cell.setFontSize(fontSize10); 
    }
}

Answer 1

当您调用table.draw()时，它返回yStart坐标，即表格在当前页面上的结束位置。您可以将它用作for循环中下一个表的输入参数yStart。

例如，在您的代码片段中

float yStart = 650;//for example
for(ProductGroup productGroup: productGroups) {
            BaseTable table = new BaseTable(yStart, yStartNewPage, bottomMargin, tableWidth, margin, doc, page, true, drawContent);
            Row<PDPage> headerRow = table.createRow(15f);
            Cell<PDPage> cell;
            createHeader(headerRow, table);
            Row<PDPage> row;
            for(Article article: productGroup.getArticles()) {
                row = table.createRow(10f);
                cell = row.createCell((100 / 9f) , article.getBranch().replace("\n", "").replace("\r", ""));
                .....
            }
            //getting Yposition of table end
            yStart = table.draw();
            //As you are drawing multiple tables which might get split over pages, get the latest page
            page = document.getPage(document.getNumberOfPages()-1);

}

Set，yStart = table.draw()

使用对应的yStart位置创建另一个BaseTable
