May be okay for computer layout. Mobile space is valuable. Why not enter number of rows and columns and add / remove with one button click? + enter field for #

ROWS [#] buttons [+] [-]
COLUMNS [#] buttons [+] [-]

Mean adding a number field. Then user can put in single digit number. Then click add (+) or remove (-). Either was is all good of course. Much better than a user needing to know markup language to build a table. Keep up the great work!

Was thinking with table creation. # rows and # columns. Not often one would come back to the table to remove rows and columns with mostly immutable blockchain data practices. Just a suggestion though.
