我想要 PDF 中的表格数据，我正在使用以下命令获取表格数据

java -jar tabula-java.jar -a 301.95,14.85,841.0500000000001,695.25 -t example.pdf

但是在这种情况下，两列数据在某些行中混合在一起，所以我想指定列坐标以获得完美的数据，但我不知道如何获取列坐标，所以任何人都可以用完美的命令指导我会有所帮助。

提前致谢！

您可以使用 -c 或 --columns 参数指定列坐标。您指定的坐标将是列之间的轮廓线的坐标。因此，如果一列从 10.5 变为 13.5，而下一列从 13.5 变为 17.5，那么您只列出 13.5。您还需要关闭猜测。您没有提供示例 pdf，因此我无法为您提供正确的坐标，但您的命令看起来像这样：

java -jar tabula-java.jar -a 301.95,14.85,841.0500000000001,695.25 -c 15.7,17.3,19.2,33.2,70.1,100.7,200.6,300.7 -t example.pdf -g False

您可以从帮助命令中阅读更多有关获取命令的不同选项的信息：

    $ java -jar target/tabula-1.0.1-jar-with-dependencies.jar --help
usage: tabula [-a <AREA>] [-b <DIRECTORY>] [-c <COLUMNS>] [-d] [-f
       <FORMAT>] [-g] [-h] [-i] [-l] [-n] [-o <OUTFILE>] [-p <PAGES>] [-r]
       [-s <PASSWORD>] [-t] [-u] [-v]

Tabula helps you extract tables from PDFs

 -a,--area <AREA>           Portion of the page to analyze
                            (top,left,bottom,right). Example: --area
                            269.875,12.75,790.5,561. Default is entire
                            page
 -b,--batch <DIRECTORY>     Convert all .pdfs in the provided directory.
 -c,--columns <COLUMNS>     X coordinates of column boundaries. Example
                            --columns 10.1,20.2,30.3
 -d,--debug                 Print detected table areas instead of
                            processing.
 -f,--format <FORMAT>       Output format: (CSV,TSV,JSON). Default: CSV
 -g,--guess                 Guess the portion of the page to analyze per
                            page.
 -h,--help                  Print this help text.
 -i,--silent                Suppress all stderr output.
 -l,--lattice               Force PDF to be extracted using lattice-mode
                            extraction (if there are ruling lines
                            separating each cell, as in a PDF of an Excel
                            spreadsheet)
 -n,--no-spreadsheet        [Deprecated in favor of -t/--stream] Force PDF
                            not to be extracted using spreadsheet-style
                            extraction (if there are no ruling lines
                            separating each cell)
 -o,--outfile <OUTFILE>     Write output to <file> instead of STDOUT.
                            Default: -
 -p,--pages <PAGES>         Comma separated list of ranges, or all.
                            Examples: --pages 1-3,5-7, --pages 3 or
                            --pages all. Default is --pages 1
 -r,--spreadsheet           [Deprecated in favor of -l/--lattice] Force
                            PDF to be extracted using spreadsheet-style
                            extraction (if there are ruling lines
                            separating each cell, as in a PDF of an Excel
                            spreadsheet)
 -s,--password <PASSWORD>   Password to decrypt document. Default is empty
 -t,--stream                Force PDF to be extracted using stream-mode
                            extraction (if there are no ruling lines
                            separating each cell)
 -u,--use-line-returns      Use embedded line returns in cells. (Only in
                            spreadsheet mode.)
 -v,--version               Print version and exit.
