Initially, a table with one row and a certain number of columns. I want to ask you whether it is possible to divide each cell (td) into a given number of rows, starting from this column and continuing to the last column

Say the above table is my original table and that in the first column I decided to split it into 2 rows, this separation should also apply to all subsequent columns

As you can see, dividing the first column into 2 rows also split the next column into 2 rows.

Then, if I decided to split the second column into 2 rows, this separation should only apply to columns starting from the second column. It should not touch the first column.
