    <p>There is no direct method in the current source code:</p> <p>This is how the style is created:</p> <pre><code>public HSSFCellStyle createCellStyle() { ... ExtendedFormatRecord xfr = workbook.createCellXF(); short index = (short) (getNumCellStyles() - 1); HSSFCellStyle style = new HSSFCellStyle(index, xfr, this); return style; } </code></pre> <p>with </p> <pre><code>public short getNumCellStyles() { return (short) workbook.getNumExFormats(); } </code></pre> <p>and (in InternalWorkbook)</p> <pre><code>public int getNumExFormats() { ... return numxfs; } </code></pre> <p>and with the workbook.createCellXF() resolving to:</p> <pre><code>public ExtendedFormatRecord createCellXF() { ExtendedFormatRecord xf = createExtendedFormat(); records.add(records.getXfpos()+1, xf); records.setXfpos( records.getXfpos() + 1 ); numxfs++; return xf; } </code></pre> <p>So what is possible from the HSSFWorkbook, is to call:</p> <pre><code>InternalWorkbook getWorkbook() { return workbook; } </code></pre> <p>and then on the InternalWorkbook object:</p> <pre><code>public ExtendedFormatRecord getExFormatAt(int index) { int xfptr = records.getXfpos() - (numxfs - 1); xfptr += index; ExtendedFormatRecord retval = ( ExtendedFormatRecord ) records.get(xfptr); return retval; } public void removeExFormatRecord(ExtendedFormatRecord rec) { records.remove(rec); // this updates XfPos for us numxfs--; } </code></pre> <p>So to make it short, from the top workbook, something like this:</p> <pre><code> InternalWorkbook w = workbook.getWorkbook(); ExtendedFormatRecord record = w.getExFormatAt(index); w.removeExFormatRecord(record); </code></pre> <p>This is all very horrible :)</p>

    1. COI think that might lead me to something. I just took a quick look at the ExtendedFormatRecord and it seems to me that both styles and cells are ExtendedFormatRecords. If I figure out the correct number of style in this index I believe I might be able to remove it. However, I am afraid that all of the references from cells to (removed) style will get corrupted...

    2. COYou'll need to fix up references too, otherwise things will break when you shuffle the order of the XFs around with the removal. Take a look at HSSFOptimiser to see what's required to be done!

    3. COAlthough this is not the full answer to my question, this simple copy past of poi source code pointed me to the right direction. Thanks!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
