How To:
Manage Matrix Brackets

Prior to the upgrade to Maple 2015 we could always use Equation Editor to bracket a text-based table by putting EE brackets in the end columns of the table:

[

Table objects

are placed

 in here ]
e.g.

answer

fields

After that upgrade, as you can see, the EE brackets no longer automatically stretched to fill the cell. You now have to set the bracket size manually.

To do this, use EE to place a bracket of the desired orientation. Then source-edit that object and place an mspace tag within it (anywhere, I use the position just before the closing math tag). The following are suggested sizes:

  1. mspace height="7ex"/ for 2 rows
  2. mspace height="10ex"/ for 3 rows
  3. mspace height="12ex"/ for 4 rows
This code needs to be in angled brackets (which I cannot show here) and make sure you include the ending slash / shown. There also tends to be extra line breaks inside tables which need to be removed for these sizes to work.
