How to show a table of values

A table is a grid of text cells drawn in a corner of the chart. Create it once, keep its handle in a static variable, and fill the cells on barstate.islast, so the work is done for the one bar the reader looks at and not for every bar of the history. table.new(position, columns, rows) makes the grid and table.cell(table, column, row, text) sets a cell; columns and rows count from 0. Cell text is a string, so convert numbers with str.tostring.

//@lipi=2
indicator("Last bar summary", overlay=true)
static table info = table.new(position.top_right, 2, 3, border_width=1)
if barstate.islast {
    table.cell(info, 0, 0, "Close")
    table.cell(info, 1, 0, str.tostring(close))
    table.cell(info, 0, 1, "High")
    table.cell(info, 1, 1, str.tostring(high))
    table.cell(info, 0, 2, "Volume")
    table.cell(info, 1, 2, str.tostring(volume), bgcolor=color.new(color.blue, 0.2))
}

table.cell also takes textcolor, bgcolor, size, width and height. To change only the text of a cell later, use table.cell_set_text(table, column, row, text).

Limits

Position is one of the nine position.* constants (position.top_left, position.middle_center, position.bottom_right, …).
A chart holds one table per position. Creating a second table at the same position deletes the first, so a script has at most nine tables.
Cell text is at most 999 characters; a longer string stops the script when it runs.

The mistake to avoid

Calling table.new on every bar. Each call makes a new table that replaces the one at that position, so the table is rebuilt on every bar. Create it once in a static variable, as above. See Tables.
