Click any text to edit. Table 1: use ＋ − ⚙ above each column and beside each row to add/remove/configure; drag a column border or a row’s bottom edge to resize. Table 2: type or paste rows from Excel — font shrinks only down to about 6 pt, then rows continue on the next A4 landscape page (each page is shown separately below). Ctrl+Z / Ctrl+Y undo and redo anything. Drag across cells (or Shift+click) to select a block — Delete clears it, Ctrl+C / Ctrl+X / Ctrl+V copy, cut and paste like Excel. Everything is saved in this browser; use Export / Import to move it.
