A DESCRIPTION OF THE REQUEST :
User is unable to select multiple contiguous rows within a table using Shift+Control click.

If the user hold down the Shift key and select a start and end row, then row start through row end, inclusive, will be select. Then, the user should be able to hold down the Shift and Control keys and select a new row start and row end. Both selections should be selected.

This process works for most file browsers and operating systems by default.

JUSTIFICATION :
This saves time multi selecting non-contiguous elements in a table and reduces the chance of a user accidentally selecting outside of the box, which could potentially clear any selection.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
When using Shift+Control keys, the user should be able to select multiple contiguous selections inside of a table. A user can hold down shift while selecting a start and end row, this selecting all rows between the start and end. If the user then holds down shift and control keys, they will be able to select another contiguous selection within the table; retaining the prior selection.
ACTUAL -
Once the user has selected the first contiguous selection in the table, holding down shift and control while clicking a start and end row will simply just select those two and not the selection between the start and end. The first contiguous selection is retained.

CUSTOMER SUBMITTED WORKAROUND :
Only workaround is to non-contiguously select all other rows that the user desires to be selected.
