For "a while" now, most websites have made it so that the only way you can grab data is to put the cursor in the first cell of the table, and click-drag down & across to the lower right of the table, keeping the cursor in the last cell of the table, ctrl-c or edit/copy, then pick a cell in your spreadsheet of choice and either paste, or paste-special values.

This is because they present (bury) the data in the response inside of javascript objects, so older & simpler methods like Excel's query/html or Google Sheets' IMPORTHTML table just get nothing.

With Barcharts, getting historical data added another tedious step - pasting puts every cell in one column. I had to write a gscript in Chrome's macro module to then parse each cell value into a 7 column wide row.
