Empty spaces between rows

Bug Report

Description of the problem

I've noticed two very strange issues with the tables:

If a row doesn't fit entirely on the page, it gets fully pushed to the next page, creating empty spaces.
If the text is too long to fit, it gets cut off with an ellipsis.

I would appreciate it if anyone knows how to fix these problems.

Code sample

this.document
    .table({
        debug: true,
        defaultStyle: {
            border: 0,
        },
        rowStyles: {
            padding: {
                right: 10
            }
        },
        columnStyles: [80,   '*'],
        data: [
            [
                {
                    rowSpan: 2,
                    text: 'LEFT_COLUMN'
                },
                'RIGHT_COLUMN'
            ]
        ]
    });
});

pdfkit version: 0.17

This was intentional behaviour to ensure the borders of the cell render correctly.
This issue should be fixed by Fix precision rounding issues in LineWrapper #1595

@hollandjake

@hollandjake, thanks for the quick reply! Just wondering — how do other libraries typically handle this? Long tables are pretty common in PDFs

@blikblum

var dd = {
    pageSize: {width: 500, height: 200},
	content: [
		{
			table: {
			    columnStyles: [100],
				body: [
					[{text: 'LEFT_COLUMN', rowSpan: 3}, 'RIGHT_COLUM_ROW_1\n'.repeat(5)],
					[null, 'RIGHT_COLUM_ROW_2\n'.repeat(5)],
					[null, "RIGHT_COLUM_ROW_3"]
				]
			}
		},
	],
}

This is the outcome of pdfmake.

@blikblum is this intended behaviour?

@monolithed is this more of what you had in mind?

@hollandjake

@hollandjake yeah, that's what I had in mind.

@blikblum is this intended behaviour?

The pdfmake behavior seems reasonable

I'd like to see also like other libraries does, like iText or QuestPDF.

We should incorporate their experiences in designing and PDF api

Can you add an test (unit or visual) that fails currently and passes with the PR?

@blikblum Which PR do you want that in?

@blikblum Which PR do you want that in?

The precision that is already open

@blikblum

@blikblum now added visual test

@blikblum

@blikblum, how long you think it'll take to fix?

Waiting for feedback of pdfmake dev

@blikblum

@blikblum for reference itext outputs the following

@hollandjake

@hollandjake, probably it depends on the specified margins, but it looks standard-perfect

im just running QuestPDF for reference, will update when ive got that running

QuestPDF output:

any feedback on when this will be fixed ?

@makyson

any feedback on when this will be fixed ?

@makyson no target date yet. Having split columns over multiple pages is hard because content can be aligned vertically, which means it may have vertically centered text spanning multiple pages, any ideas would be greatly appreciated

Just checking any updates on this?

Apologies ive not been able to find any time to investigate and resolve the underlying issues (numeric precision) which are blocking the development of this. If anyone else if able to find the time please give it a try
