Hi Derek,
Syncfusion Greetings.
We achieved your requirement by making use of CSS. Please refer below sample.
.e-schedule .e-timeline-month-view .e-date-header-wrap table col,
.e-schedule .e-timeline-month-view .e-content-wrap table col {
width: 10px !important;
}
Note: The width of the work cells should not be reduced below its min-width(22px). When we minimize the width of the workcell < 22px the appointment will be mispositioned.
Regards,
M.Vinitha devi
