Page break within a table component

[mpsbhat]

Namaste,

I'm checking some conditions to have a pagebreak within a table after a particular row count. Below is a sample code for the reference.

        var dd = {
                  content: [
                      {
                          table: {
                              dontBreakRows: true,
                              headerRows: 0,
                              body: [
                                  ['row Header', 'column B'],
                                  ['row 1', 'column B'],
                                  ['row 2', 'column B'],
                                  ['row 3', 'column B'],
                                  [{text: '', pageBreak: 'after'}, ''],
                                  ['row 4', 'column B'],
                                  ['row 5', 'column B']
                              ]
                          }
                      },
                  ]
              }

In the above sample when i comment headerRows: 1, in table definition then it breaks the table to next page as expected. But when headerRows: 1, is enabled then there is an extra blank page appends soon after breaking the table to next page. Any possibilities to handle this case to avoid the extra blank page?

Having the same problem here. Any update on this?

@mpsbhat Page with tables are pretty tricky in this library and don't break rows has uncovered edge cases. I've personally not had a lot of success with dontBreakRows and instead use a workaround to get stable page splitting based on whether content fits on page. Not sure if this helps though.

Other notes on quirks:

• Empty strings "" don't get rendered but single space does " ".
• pageBreak: 'before' will break before the unrendered text node instead of before the table row.

What's could be happening is that the second column is getting rendered, then page-break, then the left column but since it's "bigger than one page" it renders a whole extra page.

Try putting spaces in and another header row after the page break and see if it works for you.

        var dd = {
                  content: [
                      {
                          table: {
                              dontBreakRows: true,
                              headerRows: 0,
                              body: [
                                  ['row Header', 'column B'],
                                  ['row 1', 'column B'],
                                  ['row 2', 'column B'],
                                  ['row 3', 'column B'],
                                  [{text: ' ', pageBreak: 'after'}, ' '],
                                  ['row Header', 'column B'],
                                  ['row 4', 'column B'],
                                  ['row 5', 'column B']
                              ]
                          }
                      },
                  ]
              }

Here's my workaround for reference.

@olafur-palsson Namaste,

As mentioned in my comment itself, the code works even if there is no space in the case of headerRows: 0 but it adds an extra page for headerRows: 1

Screenshots attached for reference.

I have the same, or similar, issue. The pageBreak 'after' inserts an empty row under the header of each subsequent page (page 1 is ok). This in turn results in an extra page at the end of the document which just has the header and a very thin empty row. I have confirmed that the data structure pushed to 'dd' does not contain extra empty rows.
