Manual column break problem

Hi everyone, am having a problem with a particular manual column break in the following document:

NEW List of aspects to consider whilst practicing drums.odt

I can’t seem to get the column to break in the third column at the cell with the grey background that reads “TIMING”.
I want it to be at the top of the 4th column.

I have tried inserting manual column breaks in various places- I would have thought that positioning the cursor to the left of the “TIMING” text then inserting a column break there would have done the job, based on the following information:
“Column Break
Inserts a manual column break (in a multiple column layout), and moves the text found to the right of the cursor to the beginning of the next column. A manual column break is indicated by a nonprinting border at the top of the new column.”

Source: Insert Manual Break - LibreOffice Help

But apparently not as nothing happened as a result. Clearly I don’t understand how these breaks work well enough.

If someone could please explain where the manual break should be inserted and why then that would be swell!

Thanks helpful people!

This is a table, not text flow in columnar layout (which is defined using Columns in section’s, table’s, or page’s properties). You cannot do that with table cells.
