Feature/#226 create table rich component

[oleojake]

First implement only header and rows (no column size calc).

Let's create a table.business.ts file and move this functionallity to simple functions that can be unit tested (and let's add some defensive code), e.g. a given user can enter text with blank content or just one row.

./table.business.ts

export const parseCSVRowsIntoArray = (csvContent : string) : string[]=> {
}

export const extractHeaderColumn = (row : string) => string[] => {
}

export const extractDataRows = (rows : string[]) => string[][] => {
}
