I don't think this is the right place to ask questions for non-appian related doubts. And there should be some examples already on the web for this. If not, ChatGPT should help you. 
 And if you want to build this on Appian only for practice, then I think you can simply take up the total number of setas (assuming that there is not gaps or divisions) and then arrange them in a matrix. Here is my blog on how to do that - appianspace.com/.../

a!localVariables(
 local!columns: 10,
 /*Pass it dynamically */
 local!rows: 10,
 local!theaterSeating: 
 a!forEach(
 items: enumerate(local!rows) + 1,
 expression: a!localVariables(
 local!rowNumber: fv!index,
 a!forEach(
 items: enumerate(local!columns) + 1,
 expression: a!map(
 rownumber: local!rowNumber,
 columnnumber: fv!item,
 selected: false
 )
 )
 )
 )
 ,
 local!Seats:
 a!refreshVariable(
 value: a!flatten(local!theaterSeating),
 refreshOnVarChange: {local!theaterSeating}
 ),
 local!selectedSeats:a!refreshVariable(
 value: index(local!Seats,wherecontains(true,toboolean(local!Seats.selected)),null),
 refreshOnVarChange: {local!Seats,local!theaterSeating}
 ),
 
 {
 a!cardLayout(
 contents: {
 a!forEach(
 items: local!theaterSeating,
 expression: a!sideBySideLayout(
 items: 
 a!forEach(
 items: fv!item,
 expression: a!sideBySideItem(
 item: a!richTextDisplayField(
 value:a!richTextIcon(
 icon: if(fv!item.selected,"square-full",
 "square-o"),
 link: a!dynamicLink(
 saveInto: {a!save(fv!item.selected,if(fv!item.selected=true,false,
 true))
 }
 )

 ))

 }

 Take a look at this code Shravani , I don't prefer it because if the rows are columns are too high, data on the interface ( in map) gonna be large so leads to performance issues (interface might gets slow), So go for alternatives. Or if you find any alternative within appian let us know
