I will modify `src/pages/admin/ExamTaskPage.tsx` to optimize the user selection display and the table layout.

**Implementation Steps:**

1. **Optimize User Selection (`Select`** **Component):**

   * Add `optionLabelProp="label"` to the `Select` component.

   * Update `Select.Option` to include a `label={user.name}` prop.

   * This ensures that while the dropdown still shows "Name (Phone)" for clarity, the selected tags in the input box will only show "Name", saving significant space.

2. **Optimize Table Layout (`columns`** **Configuration):**

   * **Task Name & Subject:** Add specific `width` properties (e.g., `200px` and `150px`) and `ellipsis: true` to the "Task Name" and "Exam Subject" columns to give them more space and handle overflow gracefully.

   * **Action Column:** Change the `<Space>` component in the "Action" column to `<Space direction="vertical" size={0}>`. This will stack the "Edit", "Report", and "Delete" buttons vertically, reducing the column's required width. I will also set a fixed, narrower width for this column.

3. **Verification:**

   * Verify that selected users in the form only show their names.

   * Verify that the table "Action" column is narrower with vertically stacked buttons.

   * Verify that "Task Name" and "Exam Subject" columns are wider.
