Research direction
Investigate how Blueprint's Tab component handles rendering of child components (like Table) when not active. Check if there's a CSS issue related to display or visibility when tabs switch. The provided sandbox (https://codesandbox.io/s/render table correctly in non active tab blueprint js 4u6iq) can be used to reproduce. Look at the tab component's lifecycle and any conditional rendering that might affect table dimensions. A potential fix could involve ensuring the table recalculates layout when it becomes visible, or using a CSS property like 'visibility: hidden' instead of 'display: none'.
