How can I add a table to a placeholder table?

[BenHall-1]

Description

I cannot work out how to update a Table placeholder with a table generated by slide.AddTable - Can you please advise?

Welcome! Thanks for posting your first issue. The way things work here is that while customer issues are prioritized, other issues go into our backlog where they are assessed and fitted into the roadmap when suitable. If you need to get this done, consider buying a license which also enables you to use it in your commercial products. More information can be found on https://unidoc.io/

Hi @BenHall-1,

Can you share the code, current PPTX result and desired PPTX result?

Best regards, Alip

Hey @sampila, sure.

func Table(slide presentation.Slide, tableIndex uint32, data XXX) *common.Table {
    p, _ := slide.GetPlaceholderByIndex(tableIndex)

    tbl := slide.AddTable()

    for _ = range data.XXX.Cols {
        c := tbl.AddCol()
        c.SetWidth(1.0 * measurement.Inch)
    }

    headerRow := tbl.AddRow()
    headerRow.SetHeight(measurement.Inch)
    for i, cell := range headerRow.Cells() {
        cell.TxBody = dml.NewCT_TextBody()

        para := dml.NewCT_TextParagraph()
        cell.TxBody.P = append(cell.TxBody.P, para)

        egtr := dml.NewEG_TextRun()
        para.EG_TextRun = append(para.EG_TextRun, egtr)
        egtr.R = dml.NewCT_RegularTextRun()
        egtr.R.T = data.XXX.Cols[i]
    }
    return tbl
}

It currently returns not_working_1.pptx

However I'd expect a result of expected_result.pptx but I cannot work out how to get it to go onto the placeholder

Hi @BenHall-1,

Thank you sharing the code and PPTX file, we will check and give you an update later.

Hi @sampila, any update on this?

Hi @BenHall-1,

Regarding this the current UniOffice only supports paragraphs inside placeholders. For positioning the table inside the slide, you can probably use the 'table.SetOffsetX' and 'table.SetOffSetY'.

See Examples: https://github.com/unidoc/unioffice-examples/blob/f47e46c076d1fc7fab6dbec68824a400c257ca54/presentation/tables/main.go#L59 API: https://apidocs.unidoc.io/unioffice/v1.20.0/github.com/unidoc/unioffice/common/#Table

Hi @BenHall-1, We released UniOffice v1.24.0 that support table placeholder, example
