## Summary

Today Alert table has a height of 600px if the number of items it
displays exceeds 20. If not, it has a height of `auto` which means it
adjust the table height according to the number of rows displayed.

This height `auto` surfaces an issue with EuiDataGrid where it is not
able to calculate the height of the displayed rows. This results in
arbitrary height everytime the number of rows < 20.

## Solution

We are working with EUI Team to permanently fix the issue. But as a
workaround, we are setting up a fixed height of EuiDataGrid to `600px`
irrespective of the number of rows that are visible on the screen. This
would sometime lead of extra flush space visible as can be seen in below
demo.

But it ensures that user is never in an unusable state. Below is the
summary of changes applied

- Fixed height of `600px` in case of Event Rendered View
