Display text from two different cells in a single line in toc

[LouisBernon]

Hello,

Is there a way to display the text of two different cells from a table into a single line in the table of content ?
This resulted in two different lines when I first tried.

I then tried to merge the two cells so I could apply the tocItem, which works, but the issue is that now the elements in the second cells are not aligned with each other because the text from the first cell is not of constant length, like on this picture :

Another solution I thought of would be to set the horizontal position of the text from the second cell relatively to the table but that doesn't seem to be possible.

My attempt with the merged cells :

let table_lot = {
    margin: [0, 0, 0, 0],
        table: {
            widths: [30,'*', 20, 34],
                body: [[{
                    text : [
                        {text: "0.0.1 -  "},
                        {text :`Documents`}],
                    style: 'h3',
                    tocItem: 'tocId',
                    tocStyle: 'toch3',
                    colSpan: 2,
                    border: [true, true, true, false],
                },
                {},
                {
                    text : "15",
                    rowSpan: 3,
                    border: [true, true, true, true],
                },
                {
                    text : "m²",
                    rowSpan: 3,
                    border: [true, true, true, true],
                },
                ],

Thank you in advance !
