Yes, it is shifting but horizontally instead of vertically. The reason is that the content of that particular collapsible section is wider than the content shown be default. Since you have not set a fixed width for your table columns, the width adjusts to the content. Hence, when the section is collapsed, the column width is adjusted to a smaller width than when the section is expanded. You can notice this by the fact that the contents of the cells above it also shift at the same time.
