Table cell render bug

[GAOChengzhan]

This Ticket is a bug occurs when the network is large and does not have a layout:

1. OK -> Apply random layout -> Sometimes the network view is blank

2. Cancel -> No network view -> Table cells do not render correctly.

1. The network view becomes blank

This bug happens randomly and is related to the package deck.gl. Since the layout is randomized and the network size is large, some pixel project matrix becomes non-invertible during rendering. As a result, the network view fails to render and appears blank.

In summary, when no pixel project matrices are non-invertible during calculations in the deck.gl, the network view can be rendered correctly, otherwise, it would become blank. I also tried to upgrade the package version from 8.x to 9.0 but the bug still occurs from time to time.

Matrix is NOT invertible	Matrix is invertible

2. Cell Not Rendered Correctly

This issue can be resolved by checking for empty data before rendering(See src/components/DataPanel/EntryTable/VirtualizedTable2.tsx). Once addressed, selecting the "Cancel" option will bring users to the following screen:
