Colspan problem on Datatable with hidden columns and rowExpansion

[bodnarlajos]

Hello there,

I have the same problem in PrimeVue 3.6.0 which is described (and solved in PrimeFaces) in the links below, described as:

I have a table with :hidden="true" columns, because I use those to Export Data not displayed,
but when I expand a row, then the columns shrink.

https://github.com/primefaces/primefaces/issues/1037
which has a followup:
https://github.com/primefaces/primefaces/issues/2937
and see also:
https://github.com/primefaces/primefaces/issues/5211

Can you please fix it?

Is there any workaround till?

Thanks in advance,
Lajos

I've found a workaround, but that is not a clear way to do it:

Instead of using hidden columns, I made them to dynamic:

Code: Select all

          
         <Column v-for="col of exportColumns1" :field="col.field" :header="col.header" :key="col.field" :hidden="true">

And my exportCSV function looks like:

Code: Select all

        
        exportCSV() {
            this.exportColumns1 = [{field:"order_date", header:"Order date"}, {field:"fulfil_date", header:"Fulfil date"}]
            this.$refs.dt.exportCSV()
            this.exportColumns1 = []
        },

In addition, I didn't find any docs also for customizing DataTable.exportCSV() function to avoid adding hidden columns only for Export. Is there any way to avoid ot or this should be the correct use?

Okay, but what does it mean to make a ticket?
