<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Iosevka Fixed SS16"">When using constrained resize policy, it is better to set the preferred widths explicitly. Otherwise, the initial distribution is a function of default preferred / maximum
sizes which are, if I recall correctly, are 80 and 5000 respectively. <o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Iosevka Fixed SS16"">You can see that the first column has shrunk because of the change in the max width (5000 -> 500). I am not entirely sure why setting the max width of one column has such
an effect, it is certainly not used for initiali allocation except to limit the width, which is not the case in the screenshots provided.<o:p></o:p></span></p>
