When I run my Shiny app, the headers of my data tables get shifted to the left. See below.
Say this table is on Tab A.
The headers get aligned correctly when I click on a different tab (Tab B),then click on Tab A again. See below for the corrected headers.
Any idea what's causing it? Below is a simplified version of my code. Thanks in advance!

library("shinythemes")
fluidPage(title = "Segmentation App", theme = shinytheme("spacelab"),
navbarPage("Segmentation", id = "allResults",
tabPanel(value='result_scorecard', title='ScoreCard',
sidebarLayout(
sidebarPanel(
h4("Select a cluster solution to profile"),
width = 3
),
mainPanel(
verticalLayout(
helpText(strong('Summary of Cluster Solutions')),
column(DT::dataTableOutput('out_best'), width = 12),
helpText(strong('ScoreCard Table')),
column(DT::dataTableOutput('out_scorecard'), width = 12)
)
)
)
),
tabPanel(value='profile', title='Profile',
verticalLayout(
column(DT::dataTableOutput('prop_by_cluster_ind'), width=10)
)
)
)
)
