Problem 1

Please read the error message "requires ext-dom". It is complaining about a missing package or in this case php extension. Generally, when you can't install a package you can look at the required packages in its composer.json to see the complete list.

phpoffice (1.1.0 in this case) requires the following:

   "require": {
        "php": "^5.6|^7.0",
        "ext-ctype": "*",
        "ext-dom": "*",
        "ext-gd": "*",
        "ext-iconv": "*",
        "ext-libxml": "*",
        "ext-mbstring": "*",
        "ext-SimpleXML": "*",
        "ext-xml": "*",
        "ext-xmlreader": "*",
        "ext-xmlwriter": "*",
        "ext-zip": "*",
        "ext-zlib": "*",
        "psr/simple-cache": "^1.0"
    },
    "require-dev": {
        "tecnickcom/tcpdf": "^6.2",
        "squizlabs/php_codesniffer": "^2.7",
        "phpunit/phpunit": "^5.7",
