How can I minimize spredsheet more than 26 rows visible horisontial

LibreOffice 6-0.5 64 bit

THANKS! Just the way I wanted it to be.

Zoom. Slider on lower right, or click or right click on the percentage number.

More precise questions may yield more precise answers…

So then, place your cursor on a cell where you want to split and then choose either menu View → Freeze Cells → Freeze Rows and Columns, which as the name suggests freezes columns and/or rows left and top of the cursor; or View → Split Window, which leaves you with independently scrollable grid windows.

Thanks but no. I want to have window smaller horisontially. Something like split screen.
