Iterating

Iterate over rows:

for (row in df) { println(row.age) } df.forEach { println(it.age) } df.rows().forEach { println(it.age) }
val age by column<Int>() for (row in df) { println(row[age]) } df.forEach { println(it[age]) } df.rows().forEach { println(it[age]) }
for (row in df) { println(row["age"]) } df.forEach { println(it["age"]) } df.rows().forEach { println(it["age"]) }

Iterate over columns:

df.columns().forEach { println(it.name()) }

Iterate over cells:

// from top to bottom, then from left to right df.values().forEach { println(it) } // from left to right, then from top to bottom df.values(byRows = true).forEach { println(it) }
