Tables Falling Off Page in Mobile View

I am creating a calendar page for a simple website. My page is finished and looks good in desktop view. When I check to see if the page is responsive, the tables fall off the page in mobile view. I do not know why my code is not working to change the 2 columns to 1 column in mobile view. I would appreciate if anyone could point out what is wrong with my code and how I can fix it.

.Calendar, th,td{
    color: black; 
    border: 1px solid navy;
    background-color: #add8e6;
    border-collapse: collapse;
    margin-bottom:1%;
    margin-top:1%;  
}

.eventDay{
    background-color:red;
}

.div_left, .div_right{
    display: flex;
    flex-flow:column;
}
.row_main{
    display:flex;
    justify-content: space-around;
}
.column{
    -moz-column-count: 2;
    -webkit-column-count:2;
    column-count: 2;
    display: flex;
}
@media screen and (max-width: 480px){
    .column{
        -moz-column-count:1;
        -webkit-column-count:1;
        column-count:1;
    }
    .row_main:{
        flex-flow:column;
    }
}
<div class="row_main">

</div>

Answer

Add flex-direction: column; for the .row_main container in the media queries for mobile to place the flex items below each other (instead of the default which places them next to each other, i.e. in a horizontal line)

.Calendar,
th,
td {
  color: black;
  border: 1px solid navy;
  background-color: #add8e6;
  border-collapse: collapse;
  margin-bottom: 1%;
  margin-top: 1%;
}

.eventDay {
  background-color: red;
}

.div_left,
.div_right {
  display: flex;
  flex-flow: column;
}

.row_main {
  display: flex;
  justify-content: space-around;
}

.column {
  -moz-column-count: 2;
  -webkit-column-count: 2;
  column-count: 2;
  display: flex;
}

@media screen and (max-width: 480px) {
  .row_main {
    flex-direction: column;
  }
  .column {
    -moz-column-count: 1;
    -webkit-column-count: 1;
    column-count: 1;
  }
  .row_main: {
    flex-flow: column;
  }
}
