Hi Ton,
We have reviewed your query and understand that you are
facing an issue with the Tooltip position for the Button component.
Upon further validation with the shared sample, we have identified that the Tooltip
is set to target the entire Grid column. By default, the Tooltip
is rendered at the center position of its target, which is why you are
experiencing the Tooltip appearing in the button column's center
position.
For your reference, we have attached a screenshot that
illustrates the width of the "td" element, which serves as the
target for the Tooltip.

Additionally, we recommend two potential solutions to
address this issue. You can either increase the button's width to match
the column width or reduce the column width to align with the button's
width.
Regards,
Suresh.
