How to paste a text to the right of a previous text

How can i paste a block of text to the right of a previous text like this

I made this using tabs and spaces but i want a better and quicker way

You can use a two column table and set the table borders as “none”: with the cursor on one cell, press Ctrl A (that’s the English shortcut, other languages use different shortcuts) to select the whole table → Right click → Table properties → Borders tab and select the “Set no borders” preset.

Note that while editing, even if you set no borders to the table Writer will show a grey line to indicate where the table is, but no problem: that line will not be printed nor exported to PDF.
